I missed one pill of my zelleta contraceptive pill and had unprotected sex and took 2 pill on the following day my chemist advice me to take emergency contraceptive pill to make sure i dont get pregnant,after two weeks i missed a pill and had unprotected sex and just took one pill as i was advice by the chemist not to take two and just continue taking one zelleta pill if i miss any.i have been having a spot dark red period since the first time i have missed the pill,is there any chance i can get pregnant when i missed my second pill?
