Plan b

Hi! So my bf and I attempted to have sex and it didn’t work. We kept hooking up and he was still on top of me and we were both naked. He didn’t come but precum may be a factor. The glow app told me I was ovulating during this time.I took plan b within 72 hours on April 8 and a week later I started bleeding. It was brown and wasn’t heavy enough for a tampon. This lasted for about 10 days with pain in left ovary. However on day 7 of that spotting/bleeding I was supposed to get my period. I’m not 10 days late. I also took a pregnancy test the day before I was supposed to start my period and it was negative. Was that bleeding a combination of the plan b and my period? Could I pregnant?
