mini pill or combo pill?

i’m thinking about getting on the Mini pill because i am sexually active but i’ve never taken it before. i’ve taken the combination pill in the past but the estrogen in the pill makes me feel like it would make my boobs bigger and I just had a breast reduction so I don’t feel comfortable going on the combo pill again. what are some of y’all‘s experiences on the mini pill compared to the combo pill?

I just wanna get on a pill that’s going to regulate my period again too! because when I was on the combo pill my period was very regular. but I don’t know how periods are affected on the mini pill.
