I'm 5 months postpartum, only breastfeeding my daughter. I've been on the pill for 3 1/2 months now and I get my period every other week! Doctors say its because of the pill but I take the pill every night between 8/8:30 no earlier or later. And lately I've been feeling like I'm pregnant again. My husband and I don't use any other protection but not quite ready for another baby yet! Has anyone gotta pregnant on the pill before?
