On oct 2 @ 3 pm had an unprotected sex with my boyfriend. The next day 8am, i took nordette as ecp then another one again after 12 hrs. Experienced horrible nausea and abdominal cramps after. The whole week I experienced breast tenderness but not withdrawal bleeding. I took a test 7 days after my second dosage and it came out negative. But will take the test again. The problem is, 10 days after the deed, oct 12. We had unprotected sex again. Will i take nordette again? Do i really have to? I dont want to mess with my cycle again, and the side effects are too awful to experience but if i have to,. i will take one tomorrow morning. Help asap. Is there a chance that I might be pregnant?
