So this has happened to me lately and I just haven't figured out the right wording...

It is obvious now to strangers that I am pregnant. At work (a small boutique - women's clothing and bridal) a few times people have asked me, "So is this your first pregnancy/baby?" I don't want to get into a whole big thing with someone I don't know, but I don't want to ignore that I had Matthew. I have said, "It's my second pregnancy", but it doesn't feel like that's what I really wnat to say. Any suggestions would be appreciated.
