Thank you to everyone who left feed back regarding how to handle my pregnancy and the IRL support group. It is SO much appreciated! I would like to encourage anyone with an opinion to continue to leave your thoughts.
You ladies didn't let me down and I got some wonderful feedback from many different view points. For the time being, I am going to take each new member on a case by case basis as to when I will let them know about the pregnancy. My plan is to not attend the meetings in person once the bump (continuing to think optimistically) is too prominent. Even if people say they are ok with it, they might not be on that particular day.
Interestingly, I have had my first big challenge in terms of new members. The newest member is dealing with secondary infertility. She got pregnant on her first IVF and has had two failed FET's from embryos left over from that first IVF cycle. She has more in the freezer, but her RE has advised her to move on to another fresh cycle. Can I be compassionate and offer her the same support I give to others still trying for their first? I think so. Can I be sincere in that support? I will try.
