Of course not.
Keep in mind that Mother Nature is a bit quirky. The first pregnancy can take any length of time up to nine months. There have been very nervous cases where childbirth follows legitimacy by minutes.
Lol! No seriously, remember when having a child out of wedlock was something to be ashamed of? People would hide the pregnancy, even post date the birth to hide the fact.
I'm more concerned with the controlling nature of this relationship, and the timing of this pregnancy. We should maybe say prayers for Katie.
