My son is 5 months old. I'm scared I might be pregnant again. while I miss being pregnant, I have diabetes and high blood pressure that is not under control. I had preeclampsia with my son and am scared that I will get it again if I get pregnant without taking better care of myself. I want another kid just in a couple years after I have time to get in better shape for me and my family. I can't have another preemie or worse.
