I am same as Suzyq! I've used Estradot almost ever since I started HRT (apart from 3 months of Evorel sequi) - so for 7 1/2 years and yes they do stick well and are very small so no probs finding somewhere else to stick them. Use (ie change) them exactly as Evorel - twice weekly. I do Monday night and Friday morning for optimal oestradiol levels.
Utrogestan you will usually take orally at night - I am interested that doc has suggested the 25 days and I am wondering if this is because the 200 mg has been discontinued so he (I think he was male?) is prescribing what is in effect the conti dose. However it doesn't matter because I think you said you may well be almost post-meno. What happens with the 100 mg is you will be less likely to build up uterus lining if used for 25 days out of 28 and on medium dose oestrogen, but the 3 days off will let you bleed if you are going to.
Personally I wouldn't want to use it vaginally aalmost all the time - as I am on a long cycle I don't mind doing 12-14 days of this now and again!
Yes I find it mostly great too - although in my case I am affected by the progesterone about 5-6 days into it - but I am taking a higher dose than you probably will be anyway.
Good luck and keep us posted - as Suzyq says be patient!
