27weeks with cramping.

So about two-three weeks ago I was in the hospital for serve pain. They told me my cervix was at 2.3 cm and I may go into preterm labour, and my chances are higher because I had my son at 24 weeks. So they told me to take it easy and let my body handle it and if I go into labour to obviously go back in. But since I got sent home I’ve been having on and off cramping pains. Like menstrual cramps feeling. Has anyone else experienced this?

My son was different, never had menstrual like cramps.
