Nauasea nerves

I’m 8 weeks and 4 days today. I have been so nauseas with some vomiting for 2 weeks. This past Wednesday (at 8 weeks) my OB gave me phenergan and zofran to help. I started taking those and it took the edge off but was still a bit nauseas. Thursday night I took the zofran at bedtime and woke up feeling fine Friday morning but took a Zofran anyways because I usually get really nauseas but I never did. Even after the meds wore off. So I didn’t take anymore. I was burping a lot and had moments where I was exhausted but that was it. Woke up again feeling fine so no meds and then towards the end of the day was nauseas and having my ibs issues that have been really bad this pregnancy. I took nausea meds and ibs meds at bedtime. Then this morning I have had one bought of nausea after eating lunch but it only lasted 15-30 minutes. But I’m tired. I’m just really worried that this isn’t normal and something is wrong :(.
