How long to wait is completely up to each individual, and sometimes it varies by pregnancy.  With my first, I was 8-10 weeks along before I told anyone but my boyfriend.  And then, I waited quite a while to tell everyone else, but I was 19, in college, etc.  With my 2nd, my husband and I told everyone right away.  Same with my 3rd.  With my 4th, we waited until we heard the heartbeat for the first time before we told family, but we had told some close friends before that because our families are quite a distance away.  This time, I didn't tell my husband until I was 8 1/2 weeks.  My daughters found out when I was 12 1/2 weeks.  We have not told anyone else yet, but that's because we really don't want to hear any comments.  The 4th was supposed to be our last, and I don't want rude comments.  We will probably tell our close friends that live nearby next weekend, my work somewhere around Halloween, and we don't plan on telling our families until we go home at Christmas and I walk in the door pregnant.

I guess a big deciding factor for me would be whether you're going to want the support of other people, should you suffer another miscarriage.  If not, then keep it to yourself.  With your history, they may do early ultrasounds, and once the heartbeat is seen on the ultrasound, the risk of miscarriage goes down quite a bit.  Good luck!!!

Hi there :)  I'm very sorry for your loss.  Congratulations on your pregnancy though!  How far along are you?  I waited to tell anyone but close family until I was 12 weeks along.  It was just the paranoia in me.  I told my best friend but other than that, just close family.  Go with your instincts and know that you are never a failure if a pregnancy doesn't work out!  I'm sure everyone would agree with me.  Please let us know how your appointment goes tomorrow!  Sending you big hugs for a wonderful dr. visit!
