The absolute last thing I wanted to hear from my dr

Isabel
if you are ttc and still haven't had your period in two weeks call us immediately so we can recommend a specialist. 
I've spent the whole evening crying. Any words of advice would be greatly appreciated...
I guess a little bit if back story would be helpful. We have been Ttc for almost 7 months and I haven't had my period since July and every test I take comes back negative. I went to the drs three weeks ago and he out me on a 12 day dose of progesterone to triggers period, but it hasn't worked. 
Almost 5 years ago we got pregnant but didn't go through with it. The only thing going through my mind now is that we got our chance and we won't get another one.
