Pelvic girdle pain

Rainbow baby not due until Valentine's Day 2020 and I started to feel pelvic girdle pain on new year's eve. The pain has gotten to the point where it's hard to even lift my leg to put pants on. Moved up my baby shower from the 25th to the 19th with the impression that baby may come sooner but since it's been 8 years since our first baby I dont remember being this much in pain. Luckily I have DR. Appt tomorrow morning and will bring it up to see what I can do for relief considering I still have to work.
