I've only done suppositories. This is my second attempt and we're using suppositories again. When do you go in? I think our transfer will be the 2nd week in July. Good luck!!
All of them work pretty well. The suppositories are the least efficient delivery, but they make up for that by putting much more progesterone into them.
The shots are very efficient, but patients don't like them.
There are also pills, but these are not very effective on their own. They can add a little boost to other methods, though.
Avoid IVF and surrogacy in Ukraine. Ukrainian centers pay shills to post here under numerous sock accounts pretending to be patients in Ukraine. Centers using such deceptive advertising cannot be trusted and should be avoided.
