Feeling Disappointed ☹️

Tomorrow is my 8 week appointment. I'm pretty sure I was told I would be hearing the heartbeat but when I called to confirm the appointment, I was told we have to wait another 4 weeks aka our next appointment instead. I'm so sad 😭 This is my first and I just want to know that everything is ok. Thank goodness for my husband who is committed to being at every appointment, including our first one which is now going to be more about the do's and don'ts of pregnancy and some genetic testing. I just want confirmation that there's a little nugget in my belly and that he or she doing ok.
