Hypertension

I’m 36 and 4 months postpartum. My bp hasn’t back to normal yet after delivery. I had postpartum preeclampsia for my 2 babies. In my first, I took a medication for two weeks then the second one, my doctor did not prescribed me because my bp is still in borderline. Our plan is to have 4 kids but I’m worried of my bp. Actually, it’s in our genes to have high blood pressure in my mother side. Isn’t it too young to have this bp? I’m between 120-145/80-95. Sometimes it is also normal. I have no unusual feelings then.
