I started birth control today for the first time ever (got my period yesterday, today is Sunday). I took it at 10:30AM and I've had extreme nausea all day. I read that taking your birth control at night really helps combat nausea. Can I take it tomorrow at night and continue taking it at the same time each night for the rest of this pack? I'm going on vacation and I have class this week so I can't be sick all week. I won't be having sex until late March because my boyfriend isn't going on vacation with me and I'm currently still on my period. I just really don't want to be this nauseous.
