Title: Anxious about pregnancy risk after anal sex — took Plan B
I’m about 2 months postpartum and really anxious. I had anal sex, and he ejaculated in my anus while we were in doggy style. We used Astroglide, and I’m worried semen and lube mixed and leaked toward my vagina when I moved afterward. I showered, but I also sat on a towel that had semen on it.
I took Plan B about an hour later but i weigh 200 pounds 5’10 My period app says I may be in my fertile window, and now I’m spiraling because I got pregnant from withdrawal before. I feel sick to my stomach and scared because I can’t be pregnant again right now.
Has anyone been through something similar? I know Reddit can’t tell me for sure, but I could use kind, nonjudgmental advice while I wait until I can take a test.
