Early BFP and gender?

[True Blue]

Is there any study that backs this up - do people think their is any truth to it?

Basically "they" say an early BFP indicates a girl and a later BFP indicates a boy.

I think this belings in old wives takes forum, sorry!
Can it be moved?

I dont see how, the hcg levels would be the same and not be affected by gender? Also i didnt get a BFP with DD until AF was a week late, may have been my cheap tests though i will never know. With DS AF was 1 day late with my BFP.

To me it doesn't tie, I mean surely an early BFP is only linked to earlier implantation.
Also the study I have seen showed higher HCG in women over 13 weeks so again it wouldn't correlate to an early BFP.

I hope it's true in my case as this is the first time I've had a BFP this early, but I hope it's not true in your case! I've definitely seen people get BFPs at 8DPO and have boys. Do a search on Fertility friend, there are pregnant with a boy charts there with BFPs at 8dpo.

It's not true with ds3 I got my Bfp at 8dpo with afternoon pee and he is def a boy

Thanks for that It's funny the things you read and think 'pah' then niggle in the back of your mind

I've gotten BFPs at 9 dpo with both. The only correlation for me is that my very late BFPs are more likely to miscarry. But I had a clear positive at 9 DPO and great betas with a chromosomally abnormal boy and a chromosomally normal girl both. At this point in pregnancy there's no way of telling.
Hcg levels have been shown to be higher in pregnancies with girls, but only later on--I think the earliest a study has claimed to find a difference was after 5 or 6 weeks, and it's more likely that the difference isn't there until closer to 11 or 12 weeks. And even then, it's a general tendency, not a guarantee of gender for any particular pregnancy.
Early BFPs that darken over the next few days are a good sign in terms of a healthy pregnancy, but really have nothing to do with gender.

it can mean that... but it's not the rule
the reason for the theory is that girls have higher hCG than boys so will show on a test sooner after implantation, but an early implanting boy at 5/6dpo will have higher hCG than a girl implanting at 9/10dpo

Doesn't work for me. My BFPs with my healthy pregnancies have been at 10DPO (4 days before AF was due), 8DPO, and 8-9DPO (not 100% which one). They have been boy, boy, girl pregnancies. My second was a twin pregnancy and had similar betas to both of my singletons. So I don't know that any of that makes a difference so early on. But it's fun to think about
