please help me 🤦🏼‍♀️!?!?!?!?!?

so i should be starting my period in about 2 days. well i’ve been super nauseous & i’ve had the worst indigestion. i caught myself falling asleep driving in which i never do. me and my boyfriend don’t use condoms because i’m allergic & ive tried every form of birth control and it messes with my body in a bad way. idk if i should go to the doctor based on i could just be sick ? i’m just wondering if any of y’all had indigestion in an early pregnancy???? or what did you go through in your pregnancy early on??
