Cramping

I’m 33 weeks and the past few days I have been feeling like these period cramps in my lower belly. I mentioned it to my doctor today, she said just for me to watch when they happen & if they are when I’ve been up and moving. The past 2 days I’ve been at work, but today I haven’t been moving much and I’ve still been having these cramping pains that come and go.

This is my second baby. But I didn’t have any pains with my first. So this is new to me .

Anyone else experience this ?
