Help I need advice!!

So me and my guy have been having unprotected sex for a while now, wanting to have a baby, well I can no longer eat a meal without vomiting. I can snack and my stomach just kinda feels like it's burning or something, but big meals like a sandwich makes me vomit. I've also been noticing me having to pee more than normal but idk if that's just me hoping for a baby...any opinions?? Haven't taken a pregnancy test yet because I'm scared to have my hopes crushed.
