I got period delay tablets to take as we're away next week and they can get so heavy it would impact the holiday significantly. They're supposed to be taken 3 days before the start of your period but I had some light spotting today = 4 days before I was due on, so I'd not started the tablets yet. If I start taking them now are they likely to still have some effect? Potentially making the period lighter? Any personal experiences with this? Thanks!
