Fans have been left in the dark when it comes to pregnant Kailyn Lowry‘s third baby daddy — and the Teen Mom 2 star just opened up in a new blog post about why that might be the case.

Her rep previously revealed that the man in question “is a friend Kail was briefly dating. This was Kail’s choice and she is 100 percent happy. Kail can’t wait to welcome the new addition to her family this summer,” before adding that they “[didn’t] know how involved the father will be. Kail will release that information when she’s ready.”

“I think I’m most worried about the changes ahead but also that I will have this baby 24/7 by myself with no help. I’m going to be a single parent from the beginning!” she wrote in a blog post on her personal website. “You might read this and say, ‘But you made this decision.’ And I did make this decision. Just like anyone, I needed to vent and can’t help but to be nervous about all the changes but blessings ahead!”

Kail first shared her baby news back in February, which shocked fans considering one of the reasons her marriage with Javi Marroquin fell apart was because she didn’t want to expand their family.

“I am pregnant. I’m sad that I should have known that people in my life would sell me out before I was ready. Like any normal person, I want it to be a happy time. I wanted this to be a private time so I could be excited while not getting chased by paparazzi and bothered with crazy headlines,” she said at the time. “Please know this was a choice I made, I already know some won’t agree but I’ve been showered with support by the ones I love since I found out.”

“Of course, I was filmed for the show saying I didn’t want any more kids but I’m pregnant again. I know so many will have comments on this but here’s the thing — I didn’t want to bring another child into a failing marriage.”
