I had sex a day before my period, we did not use a condom. My period came as normal. Two weeks later I started spotting. Everyday it keeps getting worse. I take my pill and within an hour I bleed a bit heavier and get bad cramps. I also get a headache and sick to my stomach. I've never had breakthrough bleeding before. Something just does not feel right, weather i'm pregnant or I need a higher dose. Should I take a pregnany test? Or should I go to my doctor when the bleeding stops (if it stops)?
