Hi, I was on birth control for about 4 months, from October to January. I stopped becaue I left the country. I only had my period once since I stopped, on march 12th. On the April 21st, I had sex and the condom broke. I have not had my period since. Is it likely that I'm pregnant? I'm not able to take a test till later this week, so I thought I would ask.

It might be your body is still adjusting to stopping the pill, but pregnancy is certainly possible. Of course the only way to know would be to test.
