Thick Cervix- EPO- how long to thin?

Hi
Had a S&S yesterday but couldn't be done as cervix was still thick and 2cm long so not ready.
Just wondering if anyone else was told they had a thick cervix and how long it took to thin?
I started the internal EPO tablets last night, should i just continue to do this each night and hope it thins down within the next week?? really don't want to go into xmas

I think EPO def helps ripen the cervix. I was taking 2 internally and 1 orally, morning and night.
It took about a week for my cervix to become fully effaced and soft. However, my cervix didn't actually open, as the babys head wasn't engaged so there was no pressure on it.
