I feel like I'm doubting myself. normally i would just think AF is coming. I'm expecting her on Sunday 10/01. but I've been feeling more pregnancy symptoms. I'm about 11 or 12 dpo. I got a peak on my OPK on 09/16 & we obvs BD. am I just getting in my own head or could this be implantation bleeding. it started after we had sex earlier today. I noticed when I wiped after the shower afterwards. it wasn't rough sex or anything. so I don't think it's from that. help me!? I feel foolish asking.
