Should I get checked or wait to see?

So I had an attack on Saturday night, it lasted from 3:20am to about 8:30am when it became less painful and i was able to fall asleep. I slept most of sunday had dinner, still just sore but no worse at night. Same thing monday ate lunch but wasnt hungry for dinner. Today (Tuesday) I am still having pain, not like the original attack but im starting to wonder if it's not just soreness from the attack but maybe actually still hurting. This is my third attack this year since giving birth in December, I've had maybe 10 total over the last 3 years. I've never seen anyone about them because while they suck they were usually over withing two hours, and ive never had lasting pain other than soreness that lasted only the next day.This is by far the worst attack I've had and lasted the longest and still not feeling right today. I guess im just curious if I should go to the er or maybe wait and go to urgent care in the next day or so. I tried to make a Dr appointment yesterday but the soonest they had available was the 11th of August. I just don't want to go to the hospital if there isn't anything they can do for me.
