Pelvic pain

Currently 35w 4d and I’ve been running around like a mad woman to get things done. I ran errands on Wednesday and was super sore in my pelvic area after I got home and relaxed. Fast forward to today where I was sore waking up but now I can barely walk because it’s so painful.

Has anyone experienced this? I called the nurses line and they said to take Tylenol, use a heating pad and rest but I can’t help but to feel nervous.
