Hello! The Last Time I Got My Period Was On

Hello! The last time I got my period was on the 18th of July, and I had it for the full week and ended on the 25th. My boyfriend and I had sex Friday and Saturday. Protected with condoms, and than also unprotected. He pulled out everytime. The second time we had the condom it broke, but he didn't cum yet, and he put a new condom on about 5 minutes after. Yesterday I noticed when I wiped there was light pink on the toliet paper. Than later that night I peed and my pee was normal, a yellow color but I was wiping blood. and have been spotting. The same thing has happened today. I've also been having lower stomach pains. I'm thinking cramps. Could this be impending period? Or something different?
