Plan B Wtf

Uhhhh someone HELP BRUH

I had sex the 10th & 11th this month

(if tracking is correct with this app I’m not really sure when I ovulate but it says the 11th and since my miscarriage I’ve only had 1 menstrual since so I haven’t tracked ovulation I just went with what the app said)

& after a miscarriage I had in November me & my boyfriend decided trying again wasn’t a good time because we’re scared of a negative outcome again. I took a plan b step one the 12th around 6pm. I started my period a week early (so the 19th I started) it’s now day 13 of bleed. Some days it’s extremely heavy & other days it’s pink to over 12 hours of me having a dry pad. Cramping is on & off but not really bad very tolerable.

I’ve also googled and read that the plan b only works before you ovulate. But if anyone is to take it anytime of the month after a deed how will they know if they’ve ovulate or not? Not everyone tracks it. I heard so many plan b fails story’s and women have ended up pregnant. I would love to conceive again, but my boyfriend just isn’t ready to try again. If I do conceive it would be a blessing if not that’s okay too. It’s whatever God has planned. But what all does everyone really know about Plan B ?
