Hi! I am in need of help! I had the first day of my last menses last june 17 and I had unprotected intercourse last june 24. I took 4 pills of nordette on the same day and took another 4 pills 12hrs after which is june 25. I experienced nausea and cramps from the time i took the medicine. Today, july 1 I also had unprotected intercourse. After the deed, I experienced bleeding. Is that the withrawal bleeding from the pills? When will be the next regular menses? Is there a chance of getting pregnant? Thank you!
