I missed the first 3 pills because i was sick then had protected sex later that week after i had started taking them again, i took the three i missed at the end of the pack, my period would usually come on a monday/tuesday but it still hasn't came, i have taken two pregnancy tests, this would have been atleast 3 weeks since i had sex, am i pregnant? or is it just late because i took them three pills at the end? thankyou
