I had sex a weeks before my period and the condom broke. I took the morning after pill the very next day. The next week my period came as usual and I started on birth control pills. My period seems to be irregular because I bled for 3 days straight/ regularly and now I am bleeding 1 day and it would stop the next then start back again. I'm very nausea and sick to my stomach. Could I be pregnant or am I just over thinking?
