Public announcement?

An

We haven't had our first ultrasound yet, that sound be weds, my first actual appointment. For that reason I believe I may be 6-7 weeks. I had a one day period and I was counting that as my last cycle but after looking everything through I think I may be further along. We will know for sure weds. My Husband is so eager to post it on Facebook. There's been six people post about their pregnancy and they are like two weeks ahead of me and he's ready. I'm not quite sure yet. We've told all of the people that truly matter such as close family and friends and I'm not sure if we should announce so early. What do you guys think?

These are the pics we took today, and he wants to post them asap lol. If i agree we'll post with my ultrasound pic weds. I'm still undecided.
