NEGATIVE BLOOD TEST BUT FOUND GESTATIONAL SAC cranzysgirl TTC since Dec 2012; Fairdale, West Virginia 3 posts

Just curious as to if any has had this happen. I have three kids already. Three healthy, full term pregnancies. I had very little tenderness with the breasts with all three of them. Not alot of sickness. Never implantation bleeding. I went into the ER last night with cramping I've had for about a week now. Slight. Just enough to aggravate me. My breasts are tender and a little sore. My LMP was June 5. So Im coming up on my expected time for period. Ive had 4 negative HPTs and a negative blood test last night in the ER. BUT. they did a transvaginal US and found what they believe to be either a gestational sac or "something else" it IS in my uterus and according to them it's measuring almost 8mm. It's taking me as odd, if I am pregnant, shouldn't my blood have enough HCG to show positive. Is it common for woman to still be pregnant and have a negative blood test? I'm kind of freaking out because I want this so bad but I don't want to get too excited. How likely is it that its a cyst forming in my uterus? or does that even occur? Doesn't it have to be outside of my uterus? I have no idea, I'm completely stupid to all this. It has puzzled me so much. I go in a week for another ultrasound.

I dont think you can be pregnant if there is no hcg in your blood. It could be a cyst.

uterine fibroid?

You went to the ER for slight cramping?
You wouldn't be far enough along for a gestational sac to show. Perhaps a polyp or fibroid.

do some research on "blighted ovum" you may have developed the sac but the fetus never developed inside and even just developing the sac can fool your body into thinking its pregnant and give you symptoms. But I hope thats not the case for you. good luck

Even a BO secretes HCG though.

I've been reading all day. I hope it's nothing too serious. All they told me was they saw a fluid filled sac inside my uterus measuring almost the 8mm and if i was pregnant they put me at only 4weeks3days... I didn't expect this at all. I just thought maybe it was a cyst somewhere, now they've put the "pregnant" work inside my head

yeah this is true, it may be unlikely a BO.

If there is no HCG in your blood then you aren't pregnant. I would say cyst or fibroid tumour. Both of which would explain the cramping.

well i guess if they can't tell what it is yet, theres always a chance...i had an ultrasound at 6weeks and they only saw an empty sac, did not detect a heartbeat or anything. I was so disappointed and had to wait until i was 7 weeks, 5 days for the 2nd ultrasound and there my baby was...i was measuring 7w 3d. I will hope the best for you!
