Need advice please

It’s been 5 days since I was supposed to have my period. My fiancé and I never have protected sex and he never pulls out. We have sex pretty much every day. We’ve been trying to get pregnant for over a year now.

Over the past week my sense of smell has gotten 10x stronger, I’ve experienced diarrhea, discharge, a constant headache, a love hate relationship with food (I can’t go 2 feet from it without wanting to vomit but I also eat constantly throughout the day and I normally do not do that), every morning I wake up my stomach feels off, not like in pain, I feel nauseous and have a constant urge to vomit throughout the morning.

Is there a possibility I’m pregnant?
