It’s time to do some math, Teen Mom 2 stans! We know that our favorite Pennsylvania mama, Kailyn Lowry, is pregnant with her second baby, but the little lady has yet to tell her fans when she’s due. So, with a little deductive reasoning, we’re going to figure out just about when Kailyn’s baby with hubby, Javi Marroquin, is due to drop!

We first got the news that Kailyn was pregnant back in late March. Kail’s sister-in-law, Lidia Marroquin, broke the news to In Touch magazine that the couple were expecting their first child together (Kailyn’s second) and we were super ecstatic.

We also know that Javi let Kail for Air Force boot camp in fall of 2012 and Kail reconnected with her knight in airman fatigues for his graduation around Valentine’s Day 2013. If we figure that Kail and Javi did the deed around then, then that would put Kailyn at around 14-15 weeks pregnant right now (May 29). That means Kailyn is just about to hit her four month mark, entering her second trimester and from the looks of her baby shower photos, we think we’re pretty close.

A pregnancy is considered full term when it’s around 40 weeks, and if Kail’s already knocked out about 15, our girl’s got about 25 weeks to go, which translates to about 6 months. We’ll spare you the mathematical equations and say that it looks like Kail maybe ready to pop around late November. If we were OB-GYNs, we’d give a more accurate reading, but until Kail gives confirmation, that’s all we can guess for now.

As you know, Kail and Javi are going forward with the fall nuptials, so expect to see a pretty round blushing bride in the ceremony photos!
