Worried... cramping at 5 weeks 3 days.

Candice • I have an amazing 4yr old daughter, who was a rainbow baby! We are now expecting a rainbow baby, another princess!
I have been having this light cramping just on my left side for about 2 days now. It comes and goes and isn't really painful just annoying. It doesn't feel like period cramps, more like ligament pain. And I notice it more when I'm moving around or standing a lot. But I had a MC in Dec, and I'm just wondering if I should be worried I'm cramping this early? Anyone else with this symptom?
