Nothing will ease your mind as much as talking to your doctor. Ask if you can have u/s done beacuse you are worried. I think pregnancy is full of weird pains but it dones't hurt to check with the professional <3 All the best to you and the little one!
Its probably round ligament pains
it was before 4 about 5mins but hasnt *** bak
where was the pain and was it now and then or constant
If you are really concerned, call your doctor. It could be ligament stretching or other normal aches and pains of pregnancy.
