Im 16 and I had protected sex on feb 18 2007. It was the last day of my period and I wondered if there was even a chance I could be pregnant? My period should be coming tomorrow or Tuesday.. I have had small cramps and have been very tired and HUNGRY. I have also been going to the bathroom a lot lately. My information might not be helpful enough but I just want some thoughts.

Thank you.

Yes you still could be.. a condom is not something that will work 100%

Any time you have sex you run the risk of pregnancy. No form of birth control is 100% effective.

With that said, it sounds more like your period is about to start. If it does not, take a HPT when you are about 1 week late using first morning urine. If that is negative and your period still does not start, it will be time to make a doctor's appointment to find out what is going on.

No birth control is 100% safe, there is always a risk of pregnancy. Wait and see if you get your period on time, if not take a test in 1 weeks time using the first urine you pass when you wake up in the morning.
