I’m never late and usually start the day of or a day early, I had light pink bleeding a week after my last period and then a few weeks after that. I took a test and got a BFN. After me and my husband have sex I get a light pink bleeding but only when I wipe and it only lasts a few hours thought it might’ve been AF four days ago but I got it again last night after we did it, and haven’t had It since? Could I be pregnant and my HCG isn’t high enough to get a BFP?
