i had unprotected sex and within 24 hours consumed a contraceptive, a week later i experienced bleeding for 2 days. it was very light. the date wen my cycle was due i went for a preg urine test, it was negative. after 1 week of the due date also it was again negative. My doctor has prescribed Regestrone 5 mg 3 times a day for 3 days to induce my cycle now. is it alrite to have the med? am i pregnant?.. y am i not getting my cycles, it is 10 days post my actual date. please help.
