She announced late last year that she was expecting her first baby after struggling to conceive a child for four years.

And former Real Housewives Of Orange County star Gretchen Rossi took to social media on Wednesday to update her 734,000 followers on her exciting pregnancy journey.

The 40-year-old beauty shared photos of herself at 16 weeks, although she's now 18 weeks along, and revealed she was enjoying her second trimester much more than the first.

'As you can see I don't have much of a bump yet, but when I take it from different angles it shows a little more,' she wrote in the lengthy caption.

I'm 'enjoying my second trimester so much better! Finally feeling like a human again and have more energy! Weeks 14-17 have been a lot better for me, thank goodness!'

Gretchen added that she's been trying to ensure she doesn't get hung up on the changes and rather enjoying the miracle.

Gretchen and Slade spent four years trying to get around their fertility issues, and eventually the successful strategy for them was embryo implantation.

'It’s been such an emotional journey for us. Because of that, it’s brought us so much closer together,' Gretchen revealed on the syndicated TV series.

She later told People magazine, 'It's pretty exciting that we have our little Christmas miracle.'

This month also marks 10 years since Gretchen and Slade first met.

It will be Slade's third child as he already has two sons; Grayson and Gavin from a previous relationship.

Gretchen was a main cast member on The Real Housewives Of Orange County from season four, which started in 2008, till season eight, which ended in 2013.
