I think it all totally depends on yourself and if you end up having a Lletz of similar done at the same time.
I had a colposcopy last Wednesday with 4 biopsies taken. I felt time afterwards other than mild cramping and my emotions were abit shot at but for around 3-4 days later I was very sore and uncomfortable with heavy bleeding.
My experience is apparently uncommon and it seems most women are fine to return to work straight away if only had just a colposcopy rather than treatment aswel And they are perfectly fine.
Maybe just give yourself the rest of the day off just to be on the safe side?
id also keep a supply of paracetamol and chocolate in standby if needed.
hope this helps some.
