Help is it a period?

Tanee

So I started bleeding to days before my period. The flow was not normal and it suddenly stopped. The next day I was bleeding again but it was on and off and still not a regular flow. TMI but the blood is a pinkish brown color and I the cramps I have with it don’t even feel like my regular cramps. I have never experienced a period like this. Should I take a pregnancy test or call a doctor?
