Intense pelvic girdle/SPD pain

Hi all I’m 29+3 and all of a sudden this week have very bad pelvic girdle pain. I never had this with my first and haven’t done much differently this pregnancy workout wise. I had a pretty intense leg day earlier this week where I probably over did it a bit and was way too sore and then this kicked in. So maybe that caused it?

Any tips for relief or similar experiences? I’ve been resting a lot more and icing but it hurts to even walk, especially as the day goes on, and I can’t get comfortable sleeping it just aches all night. It’s mostly across my lower back and tailbone and then into my hips, my groin/round ligament area a bit but not as bad as the other areas.
