Diarrhea instead of Morning Sickness

Is it normal to have diarrhea instead of morning sickness?. Im 8 weeks an 2 days. I feel like I gotta throw up but it never happens.. But after I eat something doesn't matter what I'm in the bathroom🙈 I also burp an have a little bit of stuff come up with it or what feels like it but never fully comes out... This is my first pregnancy since my Molar pregnancy so I'm a worried momma everything that doesn't seem right I ask around an see if it's common.. So if anyone has any answers or like comments that would be great. An any solutions would help too! Thanks!
