Does anyone else experience cramping, in the lower belly? I explain it almost like the day before your period starts...

I’ve brought it up before to my midwife, and was told if it doesn’t go away, to call.

It doesn’t happen ALL that often, but I find when it does, it really bugs me. But not enough to feel the need to call.

I’m 31 weeks, and just curious if anyone else experiences this? (Second time around, and first was born a month early)
