Am I pregnant? I don’t know 🤷‍♀️

Okay so for the past couple days I’m been experiencing random ass heartburn, all I wanna do is eat every damn thing, I don’t know if this is part of pregnancy symptoms but my mouth has been extra watery lately, my breast starting to hurt , I really sleepy in the afternoons and I’m experiencing mild headaches.

I had sex the day before ovulation and the day after. I did not use protection. I’m only 19.. I’m kinda scared... help
