Replens is horrible stuff, full of irritants. Could I suggest you use one of the Yes products, such as Yes VM? Have a look at their website. Their products match the osmolality and pH of the vagina, so much kinder. In some areas you can get it on prescription, but if not its easy to buy online.
If it were me, I'd want further discussion about the colposcopy and why they think it's necessary. If you have VA it's bound to be red up there. Also, the Replens is probably making things worse. Perhaps the gynaecologist doesn't know much about VA?
Sorry to hear you are feeling sore, I know it's horrible.
