I'm not ready to tell yet...

Hi,

First of all...I apologize if I am on the wrong board with this question...it is NOT my intent to offend anyone.  I am 30 and have had 7 miscarriages (two ectopic...rest were antipholosophid antibody syndrome related).  Doctor confirmed yesterday that I am pregnant with #8,  Now, problem is I don't want people in general to know until I'm past where I lose them at.  But at work, there are a lot of social events where there's drinking.  When I haven't been pregnant I drink two or three glasses of wine a week. 

Now, people that know me well know this...and it seemed to raise questions when I was at a work event tonight and I repeatedly said no thank you when wine was being handed out.  I froze and wound up lying saying that I had a cold.  Just was wondering from people who have possibly been in my shoes or closer to it...is there anything else I can say that sounds believable?

Thanks!
