Fat vs. Pregnant

I am overweight. I am keenly aware of the fact and accept it for what it is. Apparently other people are confused. Over the past month my hubby and I have been approached by several people who have remarked on my pregnancy. Considering we hadn't told anyone, I was quite taken aback. I know I'm pretty chubby, but I don't look pregnant. There is still the considerable size of my belly divot to keep me from looking preggers. I suppose people aren't confused when it comes to thinking there's a baby in that belly of mine, but they shouldn't be able to notice it yet. I told my husband to find out where they heard the rumor next time someone asks him. Not knowing is driving me mad.
