high levels of hcg=early BFP

trendymom

did any of you have high levels of hcg in early pregnancy that resulted in dark lines on your pregnancy test like 5 days before AF?  I had a heavy AF last month so I know that it cant be just off.  I have multiples in my family and am just alittle anxious!

I don't know what my levels were but we didn't find out it was twins until our first u/s which was 11 weeks and my doctor (who did know my levels) did not suspect twins. ?I think that u/s is really the only way to know for sure. ?GL

Some brands of tests are more sensitive than others.  I'm not sure if you have gotten blood hcg levels drawn or not, but it could just be variation in the brand of tests.  The only sure way to tell is when you have an ultrasound.  I have heard of people on the boards getting BFP's at 9dpo with a singleton.  GL and congrats!

I got a faint BFP at 11dpo. And at 5 weeks my HCG levels were just over the top of the normal scale for 5 weeks. I didin't suspect anything. Then at our first ultrasound at 7 wk 3 d they found two obvious heartbeats and babies! Shocker!

Looking back, my levels were quite high, but you can't really know until you see them on the ultrasound

betas really mean nothing. There is a huge variance in levels that are considered "normal" for any type of pg.

My twin and singleton betas were almost exactly the same.

If you are not 100% sure when you ovulated (which you wouldn't be unless you were being monitored by an RE) then chances are you O'd earlier than you thought and got the BFP early because of that.

the only way to know if it's twins is via US.

congrats! H&H 9mo!

As some of the pp have said, your beta levels don't necessarily predict multiples vs. singletons.  I did have a faint BFP at 9 dpIUI with my twins, with a first beta of 236 at 13 dpIUI.

I got a BFP at 9dpo this time, 10dpo with DS.

I don't think there is a direct correlation either.  I didn't get a + until 2 days after my period was late and the line was super faint.  It didn't get dark until a few days after that.

You can't go by betas. Some singleton betas are higher than triplet betas. However I got a very very dark BFP at 12 dpo (first time i tested) and my betas were pretty high and my REs nurse said she "knew" it was twins.

No. I didn't test early though, I tested when I was five days late- just to be sure I was really late and that AF wasn't just beingbitchy. The only way to know if you are cooking up doubles is US. The betas/progest/blablabla don't mean jack.

I got my BFP for both DD and this pregnancy at 10dpo. Actually, this bfp was lighter (almost undetectable) at the same estimated DPO and didn't darken the heck up for dayyyyyyys.

I didn't have cause to get betas checked with DD but for this (twin) pg, they were 313 at 13dpo and 698 at 15dpo. According to betabase.info I am more in line with a twin pregnancy at that gestation but I also could've just been an outlier with a singleton. DH and I joked about it (much to his chagrin lol) before having our u/s on Friday that it could be twins.

Who knows. But for us the idea that high hcg = early detection doesn't hold true.
