Hi, ma'am, actually what happened is - my gf took regestrone tablet from 17 to 28 of last month (1 tablet at night before sleep for 12 days) to delay her periods for ongoing final exam of her college. 2 days after stopping the tablet on 30th aug her period started and went on for 4 days till 2nd sept. On 15th sept we had unprotected sex but I had withdrawn. On that day I think her ovulation was going on because she was having milk white secretion from vagina. So our problem is now her period is not started, we don't know what is happening, right now she is having an watery vaginal secretion.
