Feeling huge

Lane
I'm so excited to be pregnant with my baby boy after 2 miscarriages.  It's hard to not worry all the time about every little thing after you've had miscarriages, but I'm trying.  But lately I've just felt HUGE.  Im carrying very low and he's measuring ahead.  So I know I look bigger than some other moms at 25 weeks.  But in the last week I've had 4 total strangers (and plenty of friends) tell me there's no way my due date is right and that I've got to be farther along than I am.  Since this baby was the result of an <a href="https://glowing.com/glow-fertility-program">IUI</a>, I am beyond positive the due date is correct, but it's really starting to bother me!  The looks people give me when I swear it's not twins are ridiculous too!  How do I keep these people and their facial expressions from bothering me??
