Being over sensitive??

At work today I was discussing my hcg levels are still not back to normal and a girl in the office takes the opportunity to tell me she just found out she's pregnant and how she didn't even know how it happened because she was told she can't have anymore children. She's young and has one child that she rarely sees. On top of that she takes cans out of our recycle bin to the scrap yard for money and digs cigarette butts out of the outdoor ash tray when she's out of cigs. I just can't help think this is the last person who needs a baby and I feel like it was very insensitive to even bring it up to me when my mc is still recent.  And now I have to hold off on TTC again so our maternity leaves doesn't cross over if I get pregnant.  Am I being insensitive?
