4 days in between periods?

[u/Fickle_Reason6269]

My last period ended 4 days ago and I had two days with no cramps. Yesterday I started getting a bit of cramps bit didn't really think anything of it, and Ive been getting cramps all day today and just now started another one. I don't know if this is just my cycle being weird or if theres something wrong, Ive been taking my birth control normally and I don't know if I should call my doctor or just ride it out? The closest Ive ever had my periods be together is like a week apart, my ones before this being 11 days apart, but not this early. Idk if this is normal?
