Any other gals have to deal with people thinking they're pregnant because they have a larger tummy?

So I'm not a large person, I just have a fairly chubby stomach and I'm pear shaped. It's genetic, I'm not too fussed about it either because I'm pretty comfortable in the body I'm in, however, over the years I have had so many people ask me when I'm due. I've had this happen to me in public, at work, at parties. I've had to deal with it so often and it just makes me feel so embarrassed. Does anyone else get this? It's not fun and I don't know how to handle it.
