Can anyone tell me how to regulate my period?

My husband and I have been trying only for a month now but I know I need to regulate my period I feel like my hormones are low or something. ever since my first period I never got any signs of my period coming id just wake up and boom see blood 🙃 I didn’t start getting “signs” of my period coming until a couple years ago when I had an abortion. After I had that I started getting sore boobs a week before my period but other than that I never get cramps I don’t bleed no more than 7 days I know my periods aren’t crazy irregular but they’re not regular either and I feel like because of the abortion it messed up something in my body or something. And no I’m not over weight or anything, I am taking ovulation test but I bought the clearblue digital ones and those are expensive 🥲 We’re still in our twenties but I don’t know how else to regulate my period somehow.
