Irritable uterus

I had an irritable uterus in my previous pregnancy. It started at 22 weeks and I was in hospital three times overnight to stop contractions leading to preterm labor. Ended up delivering full term so that’s great but I definitely had to take it easy a lot during the second half of pregnancy.

I’m thirteen weeks now and I think I may have had an episode of cramping the other day after a really busy day with a lot of physical activity.

If you had irritable uterus with multiple pregnancies, did it start earlier the second time? Was it worse? Same?
