IUD contains progesterone
. The progesterone has a more potent effect locally, that is close to the uterus. You could try an over-the-counter lubricant but I do not think it will be enough. I suggest asking your doctor for estrogen
vaginal cream. I suggest using a half an applicator nightly for two weeks and then backing down to just two or three times a week as needed to maintain the benefit. There are other causes for vaginal discomfort
but this is most likely given your history. It may also explain a Pap smear
changes. I would strongly suggest repeating it once you've been on estrogen for a few months.
I will assume your doctor has checked you for STDs and yeast. I hope you feel better soon.
