Yes it smells different. I had one myself & asked my doctor about it & she said it is normal. If it smells really bad something could be wrong.
After A Colposcopy Should Your Vagina Smell?
No I don't believe so.You may need to call your doctor or nurse and tell them that you have an odour that was not there befor you may have an infection because of this colposcopy but check with your doctor.
