Im 16 and i regually feel sick surrounded by a morning. I am not pregnant i know for sure ( the last time i have sex was within december and have be having regular period since and was on the pill and used a condom at the time ). Is nearby anything else that could cause this as sometimes i only feel as though i am roughly to throw up. This only happen in a morning though, it last about 2hours and i cannot get through in a morning. Is this mundane or is there anyway i can prevent or stop it.
