My gf's periods were delayed for 2 days and we did a protected intercourse three weeks ago we did a pregnancy test and it was negative and she took two deviry 10 mg pills, will it affect her periods because she just took two pills? She generally don't have issues of delayed periods but because it got late this time she was worried and she took two pills so, what should she do now? She still haven't got my periods and it's 3 days late.
