I didn't miss any blue pills, but I might have thrown up after taking a couple of them during week 1. I get nauseous dizzy, stomach aches, and vomit a lot during the first week of being on them. I also felt numbness in my legs one day while at work. Is this normal?

Also, I had sex while on trinessa. It was during the green pill week, but my period was over. I know that this is the time when I'm most likely to get pregnant. Could I be pregnant?

One more question. I had sex with no condom on Saturday. I want to get off of this birth control. Should I wait until Thursday to stop taking them, since sperm can live in my body for 5 days?
