I have been on BC for several years now. I tired Depo, I tried several types of pills and about 6 months ago switched doctors and she put me on RAVINE. I have not had any problems until now. I enjoyed the fact that my periods are much lighter and shorter, but now all of a sudden last night I took my pill like usual. I lied down in bed to go to sleep and felt extremely nausead. I'm not sure if it is just the pills or if I might be pg, which if I am means the pill didn't work like I hoped it would. I know BC pills aren't 100% effective, So I don't know what to think about this problem, afraid to talk to my husband about it cause I don't know what he'll say cause we just got married when I started this pill. I have noticed I do get angry a lot or just want to cry a lot too. I Just don't know what to do about my issues. Anyone know what to do?
