Period cycle out of whack coming off BC

Sami

I recently came off the hormonal BC pill two months ago. I had been on it for years and my periods were always regular. The first month off it, I had my period 2 days early, but this month is been about 4 days and still no period….my boyfriend and I do have sex but always with a condom. I don’t think I’m pregnant (taken two pregnancy tests and both negative) but has anyone else experienced something similar? Do I need to go to the doctor to check for sure?
