Premature

lizzie • 28. Mommy to a 7 year old little girl, and a 3 year old little boy. pregnant with baby #3 🤰🏼
Wondering if being born premature is hereditary? I was born at 30 weeks, and I'm currently pregnant actually I'll be 30 weeks next Thursday and I'm wondering if I should be concerned or careful from here on out? I'm kinda nervous about it, I don't want her to come early like I did!
