Pregnancy risks

I’m 26 and have always wanted to have children. I’m financially stable and dream about having a baby almost every night. I can’t wait to start my own family. I’ve googled this question and asked my doctors but I want to hear from other experiences.. i had a boyfriend and was with him for two years when I was 15 and got pregnant 3 times. I hid the pregnancies from my parents and terminated them privately with the help of my boyfriends parents. I am worried that I will now have difficult/high risk pregnancies or not able to carry out pregnancy to a full term with a successful birth because of my medical history. Any insight, advice etc.?

Also, for those who decide not to have children. Why? How do you figure that out?

Thank you!!
