Advice re round ligament pain??

Eliza
Hi everyone 
I wanted to ask -- has cramping like round ligament pain started for anyone yet? I'm having moderate sudden short 3 second pain particularly on my (mostly) right side if I bend down or do other random things. Any advice? Should I call the doctor? I read online that it should be round ligament pain but clearly worry about miscarriage and then my back was sore last night (harder to get comfy lately) and I totally got worried. Ugh. Any advice on what to do / how normal this is at this point? I'm 13w1d
