Why can't I have a normal pregancy ?

1st time- preeclampsia. 2nd Early bleeding and early baby. She was born at 33 weeks. 3rd I miscarried. 4th Breech and IUGR also had to have weekly Makena injections. 5th already low fluids!!! I know some ladies have way worse issues and I don't mean to complain.. No one else I know personally has ever had any pregancy issues.. So I wonder why so much with me??? I have a good BMI, Non smoker, Zero drug use current or past, I don't drink EVER, Eat healthy and exercise, and always early prenatal care no skipped appointments! So on paper it makes no sense!!
