I started my last period on november 8th and finished on the 12th. On the 21st I had sex and the condom broke, and then had unprotected sex on the 25th. On friday night, I had sex and when I pee'd after, when I wiped a noticed a little tiny bit of blood, but only noticed when I wiped, and then again the next morning. I was due for my period on monday, but haven't gotten it, but when I took a test it was negative. Could I still be pregnant?
