I'm on CD38 of what would normally be a 28-29 day cycle. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is now 7 days late. I tested on Thursday and got what seemed like a very very very faint positive but it was a blue dye test and I heard those give false positives more often. I bought a FRER and it was clearly bfn. My period has never been this late before. My sister was two week late before she got a bfp with her current pregnancy and said it'll probably be the same for me (is hcg production rates genetic?) I also heard that being overweight (which I am) can possibly contribute to delayed hcg detection. Has anyone heard that? I haven't been able to find any credible sources to confirm that though. Do y'all think there's still a possibility of a bfp this late?
