Help please! Abdominal pains since last period

A few weeks ago before my period I got abdominal pains, it continued throughout my period and now 2 weeks later I still have them. 2 days ago I was constipated bad, yesterday it was a little better but still felt slightly constipated, by the end of that night I felt like it went away for good. Yesterday I also had a bad headache, it didn’t feel like it hurt bad but I didn’t want to pick my head up to watch tv because it hurt my head to look at it and I felt a little cold (I feel is normal to me I’m always cold) I felt nauseous and hungry but I didn’t want to eat, I took a goodies powder and ate shortly after and felt better. I don’t know how to describe my abdominal pains, they are pretty much all over and they don’t hurt bad, I just know they’re there and can feel it. I don’t think it hurts at all really I can just feel them all over. I started searching things online and it scared me. I don’t want to go to the doctor unless I have to because I have a lot I have to do. Please ladies if you’ve experienced this or maybe know what it is, have advice, anything please leave it down below. Thank you.
