Wondering if anyone can help. I’ve always had pretty regular cycles but over the last few months I’ve noticed my period arriving earlier than expected by a couple of days - I use Flo app to track.
Im going on holiday in August and my tracker is now saying I’ll be on my period for the whole week! I’ve taken Norethisterone before on holiday with no issue and will do so again if it looks like it will fall during this week. However I know you’re meant to take it 3 days before your period is due to start and if I misjudge this then will it still work? I’m genuinely never sure when it’s coming anymore which is so unusual for me. If I started bleeding then took it would it still work or is it too late by that point?
