Popping feeling in my pubic bone

telam07

So I'm just shy of 21 weeks with second child and I was organizing some stuff around the house (no heavy lifting!) and randomly felt a pop in my pelvic region. It was very strange. I'm not in any pain but decided to sit down awhile just in case. I googled this but everything I found talked about terrible pain. Any clue what this is or if I should be concerned? Thanks in advance.

From what I've read, it's not a problem. The pubic symphysis loosens up a little bit due to relaxin, so it can shift around. If it's not painful, don't worry about it.

I pop and crack all the time it's just relaxin starting to loosen things up

My pelvis pops almost every time I get out of bed.
