I took the pill but not properly only took it for a week kept missing some and was having intercourse. I stopped taking it all together and usually after a couple of days I would start bleeding. It's been over a week and I haven't started bleeding still! If the pill never worked at all my natural period would've started yesterday but hasn't and no sign of it. Have sore breasts but get them when about to come on anyway. Not sure if the pill has delayed everything or if I should take a test! Been pregnant twice before and miscarried. What do I do?!
