Period after plan b

My boyfriend and I had unprotected sex on July 29th. He didn’t think he finished in me and I wasn’t supposed to ovulate for another 4 or 5 days but I still took a plan b the next morning to safe. About a week after I had strange spotting. It ranged for light brown to dark brown and jelly like. I know plan b can cause spotting so I didn’t think much of it. The spotting lasted for almost a week and then everything went back to normal. I was supposed to get my period in 3 days and I started bleeding again. It’s very similar to when I was spotting last week. It started off dark brown and there wasn’t much of it and I had mild cramping. The next day it was dark red/brown and I was seeing a lot of clots. Today it’s been light brown and hardly anything there. No cramps either. I’m supposed to get my period tomorrow. Is this spotting or is it just a very light period? Please help
