I'm a 17 years old.. I had protected sex on the last day of my period which was on the 25th of july. The condom did not break. Its been a month now after I had sex and I started my period again, But its much lighter and bad cramps and back pain, also I feel bloated before and after my period. Also My stomach has been getting hard on some days and other days its normal but still feels bloated.. Is there a chance of being pregnant. We also checked the condom for any holes and there was none!
