Suggestions...

I’m 21 weeks and for about 10 days after doing effort or being very active my belly gets super hard for a little while ... no pain just a bit uncomfortable.

Since yesterday I feel very weird in my lady area ... as if it’s getting bigger or something I don’t know how to explain it or what to compare it to. Today in the shower I checked with my fingers and I could easily put two fingers inside and there was still space. Now ... I’ve never done that before so I don’t know the normal size but should I be worried if I am dilating ?
