Hi ladies just want some advice. Got some period delay tablets (norethisterone) as I’m going away on Saturday. I was due on Thursday/ Friday, and it tells you to start taking them 3 days before you are due, so I started yesterday (Monday), but have woke up today (Tuesday) and my period has started grrrr 😫 my question is if I carry on taking them will they work and stop the period?? Anyone experienced this please? Thanks
