I had unprotected sex once, took a pill right after but one day after.. I had it again but never took pills this time. A pharmacist i consulted said the first dose stays in my body long enough to prevent ovulation and to keep me from getting pregnant in both cases and later on proceeded to give me depo shots as a better safer contraception method. I haven t had my period yet but am having all signs of early pregnancy that also show when you get this depo shots.. Am torn, some help please!
