Casey Donovan’s Joyful Family Announcement After Struggles

and her fiancée Renee Sharples shared 

The Australian Idol winner, 37, and her partner are currently going through the process.

Now, the singer has completed her first embryo transfer and is waiting to see whether or not she will get pregnant.

'Today @renee.sharples and I did our first embryo transfer,' she wrote alongside a  montage of Instagram clips showing her visiting No 1 in .

'I got the 6am flight back from to Melbourne and after a massive weekend of amazing shows in it was great to be home [and in] the loving arms of my love and put my legs up... Literally.

'Thank you to the amazing team at @no1fertility and a massive thank you to @fertility_queen_dr_burmeister.'

She went on to say she was 'truly thankful' for Dr Lynn Burmeister who went 'above and beyond' to help with the embryo transfer.

'Now we wait... What will be will be. Sending all of the love, light and baby dust to all who are on an IVF journey,' Casey added.

An embryo transfer is one of the most important steps in an IVF journey, where an embryo is first placed into the uterus.

However, pregnancy does not occur until the embryo is successfully implanted into the uterine lining. 

This is usually confirmed via blood test about two weeks after the transfer. 

Casey revealed late last year that she and her fiancée Renee were .

'We've spoken about it and Renee is now over 40, so she's gone through and done her retrievals and whatnots,' Casey told news.com.au in November.

'And then I was like, well, I need to find some time to get mine out.'
