Any ideas on how to play this?

I'm 8/40 with DC4. Not planning on telling at work yet obviously. However, I seem to have a bump, rather a big one considering it must be the size of a pea. It's so noticeable that the secretary actually asked me if I was pg, and my colleague admitted he had noticed it after I told him for another, unrealted reason. I look about 4-5 months pregnant, judging from previous pregnancies.

I'm bothered because I really don't want to out myself at this point; have had mmc before and know we are far from out of the woods yet. But have seen my boss looking very thoughtfully at my belly and obv other people have noticed it. What do I do?
