Confused about ultrasound

[jazzyjay123]

I am very confused and trying to find when I conceived as there is a possibility of two fathers. However one I was with for over two years and never conceived and the other was a new partner of two months and I am now pregnant. Both used the withdraw method. I had my LMP April 11th, 2015. I had intercourse on the 22nd and the 27th. The partner on the 22nd was the same person I had been with for two years and never conceived. I took a pregnancy test on the 4th and 5th of May and both were negative. I took a pregnancy test on the 7th and it was positive. Considering I would have been 12 and 13 DPO with the first partner I thought it would be positive. At 10 DPO it was a very faint positive. I had blood drawn that night at the ER at 1 am in the morning which would have made me either 11 DPO or 16 DPO and my levels were only at 35. Another indication it was my new partner. My hormone levels were redrawn on the 11th and were 271. The doctor at the ER told me with my levels only being 35 I was only a few days pregnant. I had my first ultrasound on the 29th of May and they are saying I am measuring 7w1d. This would mean that it was my partner of 2 years. My report says
-GA(MSD) Hellman 2.84 cm 7w4d (6w5d-8w4d)
+ GA(CRL)Jeanty 0.940 cm 7w1d +/-5d
-GA(CRL)Hadlock .940 cm 7w0d

I was almost positive I was ovulating when I had intercourse on the 27th as I had all the symptoms. I also have an average of a 29-30 day cycle. My ultrasound states I am measuring further along than my LMP. Is there any way to be able to tell who the father is? Could it be possible I am actually 6 weeks pregnant and measuring at 7?

I wish you the best of luck what ever decision you choose I hope its the best one for the child :)

This is why I want to find out who the father is my Ex says its impossible it is his considering we have been together for two years and actually tried multiple times with no luck and the new partner doesn't want anything to do with me until I know it is his for sure so amniocentesis is the best solution… however I was with one partner for over two years and was monogamous we went through a breakup and my new partner and I were tested together before we decided to be sexually active so there were no worries about STD's. Thanks everyone I am just hoping the ultrasound is dating wrong

She should want to figure out who the father is. And not just tell one man he is the father and turns out he probably isn't so she is doing the right thing by trying to figure out who the daddy is And after you do figure out who the father is dont do it like that again just saying. Having unprotected sex with different man can lead to pregnancy and also easy to catch a std.

You can crunch all the numbers and run all the apps you want but the truth is there is no way of actually pinpointing what your body was doing and given that sperm can live in the body for up to six days, the only TRUE way to know is a Dna test. But I ncourage you to wait till after birth if the Dna result is that important that you need to know cause amniocentisis can pose a threat to the baby. I mean is it so dire to know that you can't wait? And will the result really matter, wouldn't the man who will be a better father matter more?

So you had sex with two different partners 5days apart? Hmm very very tricky.

Dna test.

Be careful having multiple sex partners and only dna testing will tell.

According to all my ovulation calendars my ovulation date would have been the 26th or 27th. I also researched that a crown to rump measurement of .940 cm is a 6 week gestation but my results state 7 wks. Thanks for your inputs I am thinking of doing amniocentesis to determine who the father is. at 15 DPO I would think my hormone level should have been higher than 35 and a 35 is more accurate level for 11 DPO.

This is a tricky one!If you are measuring 7w 1d then that is what you are, remember by time you have a missed period and find out you are pregnant you are already considered 4w.
In regards to the pregnancy tests, some are more sensitive then others to the hormone and can detect it earlier. So if you used different brands that may answer why one was faint positive and the others negative.
Are you able to use a calander or ovulation app to help pin point exactly when you ovulated? But remember you may not have followed your regular cycle, for example my pregnancy was planned so I calculated my ovulation. I assumed I was 9w when I had my first dating scan, but it turned out I was actually 10w which meant I concieved only 4days after my LMP not half way through my cycle like I thought.
I think your partner of the 22nd would be more likely as you would have been 15dpo ovulation when you tested on the 7th May yes? And only 10dpo with your second partner which I think may be to early for a positive.. Im not scientist or doctor so I hope this helps you a little.
At the end of the day I guess its who you want to be the father, dna doesn't always back the best father. I don't know your situation but I would suggest talking to both your partners and the only way to know is a perternaty test once the baby is born!
Good luck.

I would say you had intercourse way to close in time and only a DNA test could determine who your babys father is. On the other hand, no, early ultrasounds are most accurate on determining how far along you are so if it is says 7 weeks then I'm sure you're 7 weeks along.
