Could I Possibly be Pregnant?

I started to spot reddish orangish blood on the 1st and I’ve also spotted brown 3 times when I don’t usually spot brown untill I’m coming off my period which usually comes on the 5th. It’s not a consistent flow like a normal period & the blood is mixed with stretchy discharge like the blood is slimy. The week before that I woke up extra nauseous that I threw up nothing but stomach acid that caused my teeth to feel funny. I drank water thinking I would feel better & I threw up the water. Nipples are extra sensitive & I’m sooo bloated.
