I constantly feel sick

Ja
I know I'm not pregnant, I just started taking my first dose of Mono-Libyan (bc pill) and it says on the package that nausea and vomiting may occur. I did know they meant you'll literally feel like you need to puke all the time. I was told that it's just my body getting used to it, I'm not even a week in yet, but this sucks! Did anyone else experience this? Also how long does this usually last, or at least how long did it last for you?
