anyone else get nauseous before period (not pregnant)?

Gabi
Just gonna start this by saying I'm on the pill. But I got sick on Christmas with a stomach bug, puking and diarrhea all night 😭 my 2 cousins had the same thing and I know i got it from them. The next day I felt really nauseous and gross. Then yesterday I felt fine and dandy, but today I've been feeling nauseous again. I'm supposed to start my period tomorrow and I don't usually get it before my period but I'm wondering if it's just a normal PMS symptom? It could definitely also be from this stomach bug thing tho too. Ugh I hate it. 
I really don't think I'm pregnant, my boyfriend and i have been having sex for months now while I've been on the pill with no scares..,but then there's always the paranoid side of me 🙄
