What should I I expect from getting a colposcopy with biopsies and endometrial biopsy?

I don't know what the correct group is for posting this, so if this is not the correct group please politely let me know what the correct group is. I'm 34 (April 30th) and have 3 kiddos (14yrs, 12yrs, 16 1/2 months).

The results of my pap came back abnormal again. It was confirmed I had HPV a couple years back. My doctor wants to do a colposcopy with biopsies and an endometrial biopsy too just to be thorough. They scheduled me for this on Monday July 20, 2020 at 4pm, and they also mentioned that my cervix would be numbed with lidocaine via needle before taking the cervix biopsies, and now I'm really panicking because I absolutely hate needles and don't have much of a pain tolerance, even after having 3 kiddos (I had the epidural with all 3 and never felt the needle each time). I can handle mild to moderate cramping but nothing severe. Would 800mg ibuprofen block all the pain or should I take 2 and have 1600mg instead or combine 800mg ibuprofen with maximum strength midol or would I be better off asking for a prescription for something stronger, and if so what would you recommend I request? Thank you in advance to anyone who shares their experiences and/or pain med recommendations!
