Cramp Like Mild Pain

Hi ladies. I know it’s normal to have cramps however I’m just double checking for peace of mind.

I’m 6.5 weeks pregnant and over the last 12 hours have a constantly cramp like niggling pain on the left side of my pelvis. I had a scan a few days ago so no chance of ectopic and everything was fine at the scan too.

Everything I’m reading about round ligament pain it keeps saying it normally starts in the second trimester though, however quite a few of us ladies are getting those types of pains now so I’m assuming it’s not just second trimester?

The pain isn’t unbearable, just uncomfortable more than anything. I’m also pretty constipated which isn’t helping matters with tummy pains here and there. Thanks for reading!
