Okay so to start it off Im 16 years old. I always have protected sex. On the last day of my period (18th of june) I had sex and the condom broke. He pulled out the second it broke. And then I had it on july 1st and the condom broke again...but im positive this time that he was barely in when it ripped and took it out right after it and we both peed right before sex. Now im getting these weird lower back pains and my tummy area is feeling funny. My 28th day from my period (when i was suppose to start my next period) was Monday, but usually I get it on the 30th day which was today and I did not get it. Im worrying a little which is why I thought I wasnt going to get it today. Do you guys think Im pregnant? Or maybe a UTI? Please help!  %-)
