A💓C • Married, 33 yrs old pregnant with our 3rd. I haves 2 boys ages (14/8) and praying for my little girl.
I have self diagnosed myself. Anyone else dealing with this terrible pain!!?? Pelvic girdle pain(PGP)

I feel pain exactly as described online 

·         in your lower back

·         in your symphysis pubis joint

·         in your sacroiliac joints

·         in your groin

·         at the front and the back of your thigh

·         at the back of your lower leg

·         around your hips

·         in your pelvic floor and around the opening to your vagina and your anus (your perineum).

Hurts so much more when sitting for a long period of time and definitely at night when turning over from side to side. How's are you dealing with the pain. Any suggestions what I can do.  I go to the doctor on Wednesday so I will definitely bring it up then. I am 19 weeks
