Have you told anyone you work with that you are TTC?
No one at work knows that we're officially trying again, though I'm sure they wouldn't be too surprised to hear that we are (our DD just turned 1 and I've said that I want my kids to be close in age).
With DD we waited until the end of the first trimester, the plan is the same for this pregnancy - unless I am obviously showing before that. But with DD I didn't "show" until 23 weeks, so i don't think it should be an issue to wait until 13 weeks to tell my boss.
With DD i took 10 weeks of leave and I would expect to do the same with this pregnancy, though who knows how the timing works out and what the circumstances will be this time around. We'll figure it out when it actually happens....though my returning to work is a definite!
My employer knows and has known for a while. It was a question asked every day and I had several break downs to coworkers when 3 employees became pregnant all at the same time! Plus, with having to be at the doctor on specific days, they have to know so I can leave to have my Ultrasounds and such! They have been pretty good! I would love to wait to tell, but at this point, it will be hard because we will be so excited to have finally gotten pregnant!
My work has ALWAYS had 2 people preggers at the same time (even before I started there). So one gal has been talking lately about starting to TTC cause he hubby is SOOOO wanting it. Well my hubby recently jumped on the train and as soon as we get Mirena removed I will start TTC too. So we have kinda been talking about it. I work at a preschool andt they are super friendly with pregnant woman. My boss has jokinly said she doesnt need anyone going out on mat leave cause she has such a great team but I know if any of us got preggers she would be 100% on board. :-)
Since everyone knows I want another kid and soonish they are expecting me to be knocked up soon and will prolly be asking me every month if I am preggers yet. lol
