What Would You Do?

Apologies in advance for the length of my post!

So this happened tonight...

My sister in law is expecting baby number 2. She is five years younger than me and has been married for 3 years longer. My brother in law (husbands brother) just announced the sex of their baby to me and  a smattering of other of my in-laws in a group text. Then dear brother in law told the group that I'm "up next."

Everyone now wants to know the sex of my baby, only problem is... I'm not pregnant. I never said I was, but brother in law thought it would be funny(?) I guess to turn some attention towards me. 

I burst into tears, so thankful it was via text and not in person, but I was crushed nevertheless. 

Now I am being text-taunted by my in-laws because we've been married for over a year and I'm not knocked up yet. 

They don't know how long we've been trying or how hard it is to see AF every month OR that AF showed up a full week early... today. Which is why I'm sure this is bothering me so much. Stupid hormones all outta whack!

I am 35 and I know that babies happen when they are supposed to and I know there are many couples who have been trying longer than we have and dealt with even more disappointment than we have known and I know I'm over sensitive right now but... What. The. Heck? How do I rationalize this and move forward? I will have to see the in-laws tomorrow night sans-husband - he works weird shifts and I've already committed to the plans as I normally find his family delightful. 

HELP!
