SPD in pregnancy

Has anyone else dealt with this? I’m 20 weeks pregnant and I’ve had this since 14 weeks and it just gets worse. I emailed the doctors office this evening but they won’t get back to me till Monday. I have bad pain where my pelvis is. It especially happens when I lift on things or am on my feet. When I go to put my pants on I can feel the popping and cracking of my bones. I’ve been trying to take it easy but when I my husbands at work it’s kinda hard. Has anyone else had this? What did your doctor have you do? How did they “confirm” that you had it ?
