The news that Kylie Jenner is pregnant with her first baby came as a shock to everyone — including Kylie herself. The reality star is expecting a baby girl in February with boyfriend of five months Travis Scott. And while she's “thrilled” by the prospect of motherhood now, the initial surprise had the 20-year-old frightened and “weighing all of her options,” In Touch has exclusively learned.

“Kylie couldn’t believe her eyes when the test came back positive,” a source told In Touch. She was so shocked and scared that the source reveals she considered ending the pregnancy, explaining, “Kylie was very conflicted in the beginning about whether or not she was going to keep the baby. It was a decision that was weighing heavily on her and it wasn’t something that she took lightly."

It didn’t help that she’d been dating the 25-year-old rapper for such a short time when they became pregnant. The pair got together in April after she split from longtime beau Tyga, who “really believes” he’s the father of the child. The 27-year-old hip hop star is “blind with jealousy,” according to a Kylie source, who noted that the two had at least one pregnancy scare during their three years together, and had discussed having kids.

But while the “Rack City” rapper may ask Kylie for a DNA test, that won't be necessary. “Kylie is sure the father is Travis,” the source detailed. “She was only with him at the time she got pregnant.” Good thing Travis “can’t wait to be a dad" — the expectant parents even flew to his hometown in Texas for the social media mogul to meet his family.

So is a marriage next for the young lovers? They will tie the knot if Caitlyn Jenner gets her way. The insider says the former Olympian may urge her daughter and Travis to get married, though she doesn’t want to further estrange herself from the family after controversial memoir The Secrets of My Life. That said, the Life of Kylie star and her man are “already talking marriage,” though the mother-to-be is in no rush. “Kylie doesn’t want to tie the knot until after she gives birth. Her main priority is the baby,” the insider added.

That hesitancy likely stems from dealing with her famous family, whom she initially “dreaded” telling about the pregnancy. Surprisingly, mom Kris Jenner “was shocked, not angry” over the news — though she does have some reservations. “She worries Kylie is too young and naive,” the family source reasons. “She thinks Kylie is still in the honeymoon phase.”

Then again, the first insider said the TV matriarch is “thrilled” that three of her daughters are expecting at the same time. In addition to Kylie, Kim Kardashian is having her third child with husband Kanye West via surrogate, and Khloé Kardashian will welcome her first with boyfriend Tristan Thompson around the same time. “This is an amazing storyline that will bring in ratings and, in turn, money,” said the insider. “Kris is seeing dollar signs.”

Khloé’s pregnancy has been a long time coming, and an insider shared that she and her NBA player love have been trying for six months. She’s now taking all necessary precautions in these early weeks, and she won't make an announcement until she’s at least four months along. A source shared, “Khloé has been keeping a low profile. Right now all eyes are on Kylie, and Khloé wants to keep it that way.”

This comes after years of infertility issues for the now-33-year-old, who was unable to conceive with former NBA player ex-husband Lamar Odom. After the couple’s split, Khloé looked in to being a surrogate for sister Kim, only to have the fertility doctor tell her — in a scene filmed for Keeping Up with the Kardashians — that she had fewer follicles (which hold eggs) than is normal.

The insider concluded, “This has been such a long journey for Khloé after all of the heartache. She has wanted to carry a baby after watching Kourtney and Kim go through it.” She's also taking care of herself, cutting out drinking, eating healthily, and scaling back on her intense workouts. “Khloé has wanted a baby forever. ” the insider explained. “This is her dream come true.”
