May I Rant?

I am blessed to work in a Christian environment. Each morning, the staff meets for devotions and to share prayer requests. There are probably ten of us or so in the meeting at any one time. This morning, I had a prayer request:
"I'm going in for two different ultrasounds on Saturday, and I'm just hoping for good results."
Co-irker: "Are you pregnant?"

In front of the whole. Entire. Staff.

Now, I understand how you can hear "ultrasound" and think "baby." I do. But, back in October, I had simply shared that I was going in for a diagnostic ultrasound--nothing more, nothing less. So it's not like this came completely out of left field.

First of all, this person has made other very hurtful comments to me about how I don't have children, so I'm already very wary of discussing anything child-related around her, because she's been so mean. SECOND of all, if you thought someone was pregnant, wouldn't you ask them one on one instead of asking it in front of the entire staff?

Maybe I'm being a little too sensitive...I don't know. This is my second day of AF-like cramps, and I'm in pain. I would think implantation, but the same thing happened to me last month and we all know how that turned out. I'm worried that the pain is intensifying each month. That's not normal.
