Chelsea Houska has been here before.

Three times before, to be exact.

However, despite having given birth to a trio of children prior to getting pregnant with her fourth child, the veteran Teen Mom star has never been here before, precisely.

Which is to say:

She's never really suffered through a pregnancy like she is at the moment.

"I thought I was a pro," Chelsea told E! News this week.

"I thought, ‘Ok, I've had a boy and two girls. I know what this will be like' but this one has definitely been different. I'm definitely more sick. I have acne. I've never had that before during my pregnancy.

"This one is definitely throwing me for a loop."

Chelsea and her husband Cole announced one month ago that another child was on the way.

They subsequently confirmed that this child will be a girl.

Houska is also mother to 10-year-old Aubree, three-year-old Watson, and little Layne, who will be two years old later this month.

She's on record as saying this second daughter will complete her immediate family.

"I always say that since this one is likely going to be our last one, they are going to give us all the symptoms so we're okay with being done," Chelsea joked in her interview with E!.

Going through a pregnancy in the middle of the COVID-19 pandemic isn't ideal, of course.

But Chelsea says it's nice to be home where you "don't have to fake like you're feeling so great and have all of this energy."

That's the positive spin she's trying to put on her situation.

At the same time, though, there's obviously a certain amount of uncertainly at what's to come with the life amid a globall pandemic -- and this "is a little scary" for the mother-to-be.

Thankfully, there's always Cole.

"Oh my gosh! He is always just above and beyond," Chelsea gushed to E!, praising her soulmate.

"He's so sweet and supportive and even if I'm not feeling the greatest or look the greatest, he's always telling me, ‘Oh you're so beautiful' and making sure to lift me up.

"He's so great."

Chelsea shares Aubree with ex Adam Lind, and told a cute story to E! about telling the little girl she was gonna be big sister. Again.

"Before, we always tried to tell her in cute ways because she was younger and never knew what was going on and this time it was different," Chelsea explained.

"She's almost 11 so she knows what's going on.

"She knew we wanted another baby and she went into my bathroom and said, ‘Mom! This pregnancy test says positive.' I was like, ‘Oh! Ok, well now you know I guess.'"

Overall, Chelsea remains grateful.

Perhaps this is why she's considered the most popular Teen Mom across all versions of the franchise.

"My family is so fun and funny. I love being around them," Chelsea said.

"I just enjoy having the family, living in the country and being able to go outside and have space.

"I'm definitely taking more moments to just really soak it in and be appreciative of family and everything we have."
