Tactic for workplace harassment

So long story short, my BFF and coworker is pregnant. She told me before telling our coworkers and I knew it was going to be a 'big thing' in the coffee room. The last few pregnancies have dominated workplace conversations and led to tons of STUPID comments from coworkers about "Oooohhh you're next!" or "Don't you want kids?" and other BS that makes me want to bawl my eyes out.

So, sure enough, first day that her news is out, I get THREE dumbass comments from ignorant but well-meaning coworkers. 

So I took an active role and decided to try to counteract this effect. No one other than my BFF knew about our struggles with IF but I figure if this is going to be a long-term thing, I'm not helping myself by keeping it private and being subjected to stupid comments all the time. So BFF was instructed to share the news. Not in the 'stand on the table and announce it' kind of way, but just to mention it to a few coworkers at appropriate times. We're a small enough building that news spreads relatively quickly and I'm pretty sure a good handful of people know now (of course, they'd never bring it up - most of them would feel so awkward they would never speak of babies in front of me again: mission accomplished). So far, no stupid comments. I fully understand a person shouldn't have to feel obligated to share their private information, but for me, this has been the right choice. Just thought I'd share!
