15weeks cramping that cause …

Im 15weeks. I have cramping on and off.

Before I got pregnant, I would cramp heavy when ovulate, it would always cause me to have diarrhea. Not sure why but it was bad. Every single month.

When I became pregnant I didn’t had those cramps at all… now since a few days I have those cramps on off. Not as heavy but I caused diarrhea again.

There’s no spotting etc.

Anyone experienced that? I’m asking to just calm my nerves.
