Accuracy of Quantitative HCG blood test?

[thanx4helpin]

I had sex on 9/29 - I missed my period on 10/14 and now I'm coming up on missing it again! I took plan B after the sex when we found the condom still left inside of me :)
I've taken a good 20 home pregnancy tests, and all were negative
I took a Quantitative Blood HCG test at 14DPO, 23DPO and 34DPO and all were negative (less than 2)
I've also taken 2 doctors office urine tests.

My boobs are heavy and my tummy feels full al lthe time, I pee frequently, but no nausea, etc.
It's been 10 years since the last time I was pregnant, can't remember what signs I had way back then, but I always registered positive on my home tests about a week after I missed my period with both of my children.

My question is this - how accurate would you believe that QUANTITATIVE blood HCG tests were at 14, 23 and 34DPO?

Thanks,
Brandy

Yes, that is the morning after pill. I've gone to the doc at Planned Parenthoot - she says she doesn't know why they stopped and is totally unconcerned with my weight gain in the past week, the extra cup size of my tender boobs, my fatigue or heart burn - I feel like I'm just simply not getting answers from her at all!

Yes they would have showen up by now. When you say you took Plan B? Do you mean morning after pill? If so this could have messed uo your cycle abit. If you havent had period in the next week or so i would go to the doctors just in case as there must be a reason why all of a sudden your periods have stoped.
Good Luck

The previous poster is right! It would've shown up by now! I don't think you're pregnant. I think maybe your period is off from the plan B pills! Im not sure about the side effects of it but you should google it and find out if it's possible for it to cause skipped periods. Or if you are really concerned, make an appointment with your doctor and ask him/her why you may be missing periods! Good Luck***

They would be coming up positive if you were pregnant. They can detect them at 14DPO.
