...hrs before due to take it.? I have only been taking Micronor mini pill for 2 1/2 weeks. Im due on next wednesday/thursday. Today Saturday, i had unprotected sex and was 4 1/2 hrs late takin the pill. The info says there is only a 3 hr window. Im assuming as sperm can live for a few days and i have had a loss of hormone in my system for a few hrs there is a chance of pregnancy? I think its best to get the morning after pill to be on safe side but does that pill have oestrogen in it as i cant take that? I have decided to go back on the Depo injection as the mini pill is too easy to get wrong.
