This fall, just over one year after marrying husband Ryan Dorsey, the Glee star will welcome her first child.

"After months of changes, anticipation, and excitement it’s finally here — the third trimester!" Rivera announced in a blog for PEOPLE Magazine on Thursday. "When I reached the final leg of my pregnancy, I was ecstatic. I could see the finish line and it felt so good. Sure, my back was on fire and I was tipping the scales at numbers I didn’t think I could ever reach, but who cares?! WE’RE ALMOST DONE!"

"Being in my third trimester means hard work is ahead and every day a new body part aches or seemingly falls apart. But it also comes with its share of really fun and exciting things too," she explained.

In addition to participating in a few DIY projects, Rivera recently celebrated her baby shower, for which she chose a children's book theme.

"They wanted to create a lovely, serene environment with white and ivory tones where guests could enter a room that would keep their minds at ease,” a guest at the shower, which was planned by Sharon Sacks, told PEOPLE Magazine.

Rivera married Dorsey in July of last year, just three months after splitting from boyfriend Big Sean.
