I had unprotected sex on Oct. 9 which was nine days after my period. I took nordette ecp (4 doses the next morning at 6am and another 4 doses 12 hrs later at 6pm). I didn't experience any withdrawal bleeding or have my period. On Oct.29 I had unprotected sex again and took nordette ecp again 6hrs latr. Then I had unprotected sex days later on Nov. 2 and took nordette ecp 2hrs later. I'm so stupid! I'm PRAYING I DNT GET PREGNANT... I haven't experienced any withdrawal bleeding... but I've been super dizzy, my boobs are tender and cramps every now and then. I have a regular 30-32day cycle.
