confused..? please help!!

emily

soo not too long ago, i wrote a post saying the first day of my last period was on february 3 and lasted to february 7. i had sex on the last day of my period w my boyfriend (protected but we had a mishap where the condom had slipped off and got halfway stuck in me but we stopped immediately afterwards) and a couple days later, i started getting weird cramping which then turned severe and i had headaches and hot flashes. i was also getting weird discharge (yellow milky discharge) for about two days and when i ovulated i had brown spotting. i’m confused now because those symptoms stopped yesterday. i did take plan b on january 21st so did that just make me sick and now i feel better? or what was that? i ovulated on the 15th and my boobs are starting to get sore but my period doesn’t start for about 10 days so i’m figuring it’s just my period coming. i’m just so confused with my body rn. should i be worried? is pregnancy a concern??
