By any chance did you ask the farmacist if medroxyprogesterone had any effects with plan B sometimes certain hormones or medicines may conteract and perhaphs you are pregnant or perhaphs its just plan B side effect. Any how any time u have intercoarse you have 20% getting pregnant. When did you have sex?
Could you be pregnant?? ahhh yes, anytime you have unprotected sex, you could get pregnant...or get diseases.
Plan A (not having unprotected sex) works BETTER than Plan B if you want to avoid pregnancy!
could be pregnant, could be side effect of plan b. plan b has a 10% failure rate.
The pill doesnt work at 100% just like worriedbabe mentionned. i had protected sex, then a couple pf hrs took the plan b pill (accidents happen right?) and then still got pregnent..
maybe its a side effect, just go back to the pharmacy or ask ur dr. they would know better then we do.
