I am 25 weeks pregnant and I have been getting stiffness in the crotch area whenever I go to stand up and walk around for a little bit after I have been sitting for a while. And also I am laying down I get stiffness there in that area whenever I move my legs. I have been pregnant once before but I can't remember it if it is normal for that to happen.
Also is it normal to get heartburn pains in your mid to lower back. I had heartburn with my first pregnancy with my daughter Katelyn, and she came out with a full head of hair.
I've had horrific pelvis/back problems with this pregnancy.
Mine in the crotch are the PGP (Pelvic griddle pain) and I also have a burning that is nerves from sciatic the stiffness I get from pgp can actually prevent me from opening or closing my legs at time and my back locks up really easy I started at about 16 weeks and am now 25 weeks and getting worst each week I have spurts now where I can't walk.
I start physio next week to try and strengthen my muscles and relax my joints etc
Maybe talk to your ob about some physio
