Why would HCG levels fall and then rise?

[1faith]

My HCG levels last Thursday fell to 10.  Today I got them checked and the HCG is up to 12.  What would make it rise rather than continue to fall?  Has anyone had this happen?  I am having a biochemical pregnancy.

I just went through ivf and just found out I am pregnant ..dont know how its going to pan out going back for more blood work with my hcg level ..i was reading what you wrote and i dont know if this is even helpful to you but my doctor made me go for some kind of blood test that will tell you if you are caring antibodies that cause miscarrage  ...im so sorry

Thanks for your words...they mean the world to me. I keep thinking in the back of my mind...same thing..maybe...miracle...etc...but know that the doc is right. He searched and searched and really thought we would see something more than we did w/ my hcg levels where they were. It was just a shocked, but something we were somewhat prepared for w/ the rollercoaster my hcg levels have been. Still doesn't make the heart feel any better today. But we will wait...see if nature takes its course, and w/ Christmas and finishing up school (i teach 3rd grade). I will keep busy. We are already talking about our next (and last!) cycle. We have 3 frozen blasts (which don't defrost quite as well unfortunately) but we are going to do all we can and then be able to close this chapter in our lives (i have an 8 yr old from a miraculous conception! and a 20 mo old using donor eggs...which is what our frozens are). But we just so wanted more children. Please keep me posted!!
Happy Holidays to you!

I am so sorry to hear about how your ultrasound went.  My heart immediately sank when I heard your bad news.  I will be praying hard for you and hope that it is just too early and in a week you will see a heartbeat.  It really spoils the holidays when you are so nervous and are expecting the worst.  Keep your thoughts up as miracles happen every day.  I just hope the next miracle is for you.  

Looking forward to the next cycle I am beginning has really helped me through this rough time.  Hopefully if things don't end up turning out well for you, you will be able to start another cycle very soon.  That is the main thing that is getting me through at this point, the thought of one more chance for success.  I'll keep you posted on how my blood work turns out.  We probably won't hear until next week right after Christmas.

Again you are in my thoughts and I will keep praying for you.  I am so sorry for what you are having to go through.

well...the inevitable...we went in today for u/s and saw the sac and fetal pole but no h/b...we are waiting a week before we decide on a d&c or drugs...just numb right now and trying to take it all in.
thanks for the support.

first of all..i am so sorry! i hope that you get some answers with all that you are going through and some peace of mind and peace in your heart. you wonder how much your heartstrings can be pulled and tugged...and then they get stretched yet again...I am sure having a tentative schedule for another cycle will keep you going! and seeing another doctor will also help w/ your peace of mind. our clinic has been wonderful...and i know that has a lot to do with us "trudging" along w/ all that we have done to get the the point we are. i feel more "intimate" w/ them than 1/2 my family! hee..hee..having a good doc and clinic can help in more ways than we can imagine.
again...my thoughts with you and wishing you the best w/ your next cycle. it will be here before you know it...along with some well deserved answers!
we have another u/s tomorrow to see if we can see what the heck is going on. my hcg raised a good amount between fri and today, so we are hoping, hoping, hoping! anxious and all those emotions! we will be at 7w5d, so we really should see something if we have a healthy baby that is fighting to make it.
thanks again for your prayers and positive thoughts. they are SOO appreciated and right back at you!!! :O)

My HCG level fell to below 5 when I tested on Monday.  I have officially had a biochemical pregnancy.  I had one in June 2006 and now this one.  They are performing blood test to see if there is anything in my blood that may be rejecting the pregnancies each time I get pregnant.  They said it is not normal to have 2 biochemical pregnancies in a row with no live births in between.  I did start birth control today and am in the start of a new fresh IVF cycle.  My tentative egg retrieval is scheduled for the week of January 13.  I am going to try another fertility specialist with higher success rates and am hoping to make it to a 5 day transfer rather than a 3 day transfer.

I will keep you in my prayers and hope that everything turns out well for you.  I hope that all of your answers will be answered soon, so you can start to enjoy your pregnancy and not have to worry each day about the health of your baby.

thanks for your well wishes. how did your tests come out? sending my best your way.
we went in fri for u/s and b/d. we saw a sac and what he thought was a h/b, but he wasn't able to say for sure. hcg level was at 6600, and he wanted it to be at 7600...so another b/d tomorrow and u/s wed....just keep dragging it out. i am trying to be optimistic, hoping that this little peanut is going to pull through and is just working on his/her own time...but know that if not, then something was wrong genetically...although my heart strings are about pulled to their limit! i just want to know one way or the other. i am about at my wits end. :O)

My HCG 13 after the transfer was 21.  Then two days later it fell to 10 and then a week later it is at 12.  I go for more blood test on Monday to see where the levels are at.  I am hoping they are at 0 if the pregnancy is not going to make it.  It is harder to wait it out when the doctor is saying that the pregnancy is definately not going to make it.  My progesterone level was only .2, so I don't thiink that it could be a viable pregnancy.

Let me know how your appointment goes.  I hope things go well for you today and you come back with good news!

What did your levels start at? my hcg levels have been crazy. I would think, though, that the numbers would have gone up more for a pregnancy to still be viable, but you don't know for sure!
here's what mine did...no explanation...yet...
7 days after FET - 35
11 days - 35 NO CHANGE! they had no explanation! so we retested two days later, went up to 80.1...then two days later...only up to 113, two days later...up to 414...two days later...up to 1014...three days later...3000...so crazy! we did an u/s right at 6 wks to rule out ectopic and the doc ruled that out...so u/s tomorrow, 7 wks, to see if there is a sac/fetal pole/ heartbeat. We have been on such a rollercoaster ride, trying to stay positive but ready for whatever it may be. The doc has now ruled it down to two outcomes...miscarriage, the numbers will hit a wall and the pregnancy will stop OR we have just had crazy numbers and the pregnancy will proceed. So still waiting...which I know is what you do throughout your whole pregnancy..but just want you to know that crazy numbers can happen and you still be pregnant...don't give up hope yet!
Sending the best your way. :O)
