My wife got her period just after 3 days from the day she stopped the pills. She used to get normal period on the 17th of every month when she was on the contraceptive pills. Just after stopping the pills, she got her period after 3 days within the same month. i.e.: She got her period on 17th and stopped the pills on 22nd of the same month. So she got her period on the 27th of the same month. Is this danger or normal?
