Hi there I just need a bit more advice.. I am on regievidon contraceptive pills, last month I missed one pill so I doubled up then had sex the following day, the day after the sex was Saturday the 13th July I took planB to be extra safe. I got my period on the Monday which is correct as I always take my period on day 4 off the pill for my breakthrough bleed.. it is now my 4th day off my pill period expected today should I be worried if it doesn’t come as I have heard the morning after pill can cause confusion for a few months? Thanks
