Pain after endometrial biopsy

Good morning, I had a transvaginal scan last week, and as it showed a thickened womb lining and fibroids, the consultant did an endometrial biopsy at the same time. That was 10 days ago, and although the bleeding stopped after a few days, I have a lot of pain in my vagina, sharp pains like sandpaper, and I can't sit down. I am post menopausal, not on HRT and have not been sexually active for 6 years so I am wondering if the pain may be due to vaginal atrophy? Did anyone else have pain for a week or so after a biopsy? How long did it take to subside? Thank you :)
