Having decided to go back on the pill-I have some packs left from when I used to be on it..can I start taking it at any point during my cycle or does it have to be on the first day of my period. I seem to remember that it takes 7 days to be effective if you start mid cycle but I could be wrong and it won't be at all effctive-which I dont want!!
Anyone know for def?
Cheers
