Ride side pain

I have since 3 hours a constant pain in my ride side ( sorry tmi : low abdomen). It's not too bad. It's a 3 out of 10 I would say. But what could it be? Just searching for someone who probably had the same..

I Googled a little because I don't wanna go to the ER only if it's really bad. It can't be round ligament pain because I read that it won't last that long..

Should I be concerned ?

I am 11weeks

Thanks in advance :)
