Could I be pregnant?

My ex boyfriend as of now and I had unprotective sex about 3 weeks ago and he came inside of me. I took plan b that morning when we woke up. 2 days ago we were drinking together and ended up having unprotected sex and he came inside me AGAIN! I immediately went and used my douche in fear of getting pregnant. Nothing really came out but my period ended Wednesday and this happened thursday night and I think I am now ovulating at the moment. This time I didn't take a plan b pill bc I felt ok after douching but now it is starting to bother me. Since my period literally just went off the day before j shoukdnt be ovulating just yet am i right? So there has to be nk way I can be pregnant right?

PS: I should have followed my first mind and used condoms but I cant change what happened so please help...
