Plan B Questions

Okay, so I’m writing here to A.) put thoughts down on paper (so to speak) and B.) get some general input.

Some back story, my bf and I have been together for over a year and a half and we live together. I’m getting ready to go back to school in a year and start a new, less stressful job. We recently just worked through some big uncertainties and I think in general we just hit that point of like “Do we want this to last forever, how well do I ACTUALLY know this person, etc” point of our relationship. We’re doing much better now.

So we had unprotected sex where he came inside on Oct 10. I took Plan B the same night, and two days later (Oct 12) started bleeding. I’m only lightly spotting now, however I looked it up and Plan B only stays in your system for 3-5 days. So before the Plan B I was due to start ovulating yesterday (Oct 17). I’m wondering if I still may have ovulated on time, or if the Plan B may have delayed it or caused the egg to be expelled when I started bleeding? I didn’t take it while ovulating, and it should’ve been out of my system by yesterday anyways right? So I’m just curious what all the effects of taking Plan B I should be looking out for and taking into account.

On top of those curiosities, my bf and I had unprotected sex again (we agreed last weekend that if it happened again we wouldn’t buy Plan B again, we’d let life happen). He came inside again (or I wouldn’t be concerned/curious) and this happened on Oct 17 (around midnight Sunday morning). So now I’m wondering if I should be looking out for TWW symptoms or if my bloating and sore boobs are because of the Plan B or PMS.

I’m really just super confused. Any advice or suggestions would be great.
