"Teen Mom 2" star Kailyn Lowry talked about the "not so fun part of pregnancy" in a new tweet Tuesday, while the mystery surrounding the identity of the father of her third baby continues. Recently, a Snapchat post hinted that her producer and rumored former flame, JC Cueva, could be the father of her child.

"Got stuck with all kinds of needles today glucose test, progesterone shot... not so fun part of pregnancy," Lowry wrote on her Twitter. In another post, she said: "I want chocolate & a nap." She also tweeted that she had been without sleep for two nights.

Lowry has been updating her fans about her third pregnancy since revealing the news in February. Earlier this week she told her fans about the latest baby struggles as she prepared for the arrival of her third child.

“My poor child’s nursery has the worst paintjob ever poor thing,” Lowry tweeted on Sunday. The same day she revealed on Snapchat that JC Cueva was one of those helping her set up the nursery.

In the post, Lowry also complained that the nursery didn't come out as "gender neutral" as she wanted. The MTV reality TV star had earlier said that she will wait until birth to find out the gender of her baby. Lowry already has her two sons, Isaac from her relationship with Jo Rivera and Lincoln from her ex-husband, Javi Marroquin.

While Lowry has not revealed the identity of her third child’s father, fans speculate either of Tyler Hill, JC Cueva, or Chris Lopez of being the father.

Rumors about Lopez being the baby daddy no. 3 first made the rounds when he tweeted about his “miracle child” in a now-deleted tweet favorited by the 25-year-old mother of two. Last month, Lowry accidentally mentioned Lopez during an Instagram live session when a fan suggested she name her third child Holden.

Lowry joked: “Chris would say, ‘I’m Holden the baby!'” This gave rise to speculation that he may be the father of the unborn child, but Lowry then clarified she was referring to her friend, “Kristen.”
