Hi Sara: yes it was the endometrium, but I still had the tablet daily (they only had you on that weekly?! I'm surprised, I had a p4 reading of 80 with a failed fresh transfer using it daily) , and yes both the progesterone in oil and the prontogest are injectables - intramuscular.
P4 in oil is not cheap ( it's a compound medicine so needs to be made up) but I pay $55 per 3 shots of prontogest ( I have 1x100mg every 48hrs).
My poor thighs are battered and bruised from the injections. We all absorb things differently, but for me injectables work and not vaginally. Also using pessaries back door can be better absorption too, with little discharge.
If you are keen on the prontogest, there is a certain way to get it as it needs to be approved by the TGA as it's imported and I think Mivf have the selling rights. I can tell you more through a pm if your keen.
Sara what have you triggered with at epu? I had a meeting with a FS from brissie when he was down for a conference in Melbourne and he said, triggers with lucrin, synarel, often result in bleeding early as these drugs break down the lining...I hadn't heard this before, he said this is why he will do freeze all cycles after using these drugs.
Thanks for the good wishes girls, hoping it's our time too x
