Confused

So Ever since I started my period 5 days ago I’ve been vomiting having stinky smelling burps and bad stomach pains. My periods are normally heavy like super heavy and normally last about 7/9 days. Well I’m currently producing brown blood after the 4th day. My period was lighter than normal. I’ve been vomiting like 4/5 times a day just feeling really sick. I googled it and pregnancy popped up. Just wondering if there is a possibility that I might be pregnant?
