I am also taking 1 x 400mg pessary every evening, I was told to use the back door the night of ET but was told to use the front door for the whole 2WW and I have just been told to use the lovely things for a further 4 weeks.
You may want to check with your clinic and I am not sure if it makes a different.
My doctor said you could use front or back passage!! I don't think it makes a difference. I've opted for the back door, as i feel i've been poked around too much up the front for now, i thought i'd give her a break!
I've been advised to take two a day, one in morn, one in eve. Are you just taking the one then?
