Premature birth?

Ci

This is my second pregnancy. My daughter was born 18 months ago, full term (40+5 to be exact) and healthy. This pregnancy I’ve had lots of cramping that I didn’t have with my first, bad enough to be put off work from it at 31 weeks. Cramping stopped for a couple weeks since I have been doing less physically but has been back the past few days, and loose bowel movements as well. Wondering if any mother’s have had previous term pregnancies and then had a premature delivery with the next?
