So for a couple of years I been taking Mononessa, im almost done with this monthes im on my last two period pills (the middle ones) im outta refills on it. So im on a new birth control called Previfem im starting the new pack Saturday. Is it okay just to start the new birth control like that? Is their a risk I can get pregnant. Last week I had sex with my boyfriend but we use a condom. I just need answers please..
