What is this feeling

Sometimes I'll feel like this tight, kinda stretching sensation in my uterus. It doesn't last long, and it doesn't hurt at all, it's more of a this is kinda uncomfortable but not bad at all. Like I can continue my life through it no problem, because it doesn't hurt at all. I'll be 22 weeks tomorrow, any advice?
