Had my mare US'd today (at 21 days past last insemination). This is the first time I have US'd her post breeding, and my vet said it looks like she has a 16-17 day embryo instead of one that is 21 days old. She said it's in the right spot to be a pregnancy, but it's much smaller and more symmetrical than it should be at 21 days. I looked at the pictures in the files here, and the embryo most definitely looks more like 16 days. What are the chances that it's a cyst (or?) and not an embryo? Is it possible for a 21 day embryo to still be so round?

Thanks!!!

If you do not know exactly when your mare ovulated, then it is impossible to tell exactly what day the conceptus is. It is entirely possible that she ovulated after the insemination, and pregnancies have been seen as much as 6 days after the last breeding.

If you did not map the uterus for cysts prior to breeding, then it is possible that it is a cyst, and there is no way at this point to differentiate. In a few days time however you will be able to, as there should be a heart beat visible - which cysts generally tend not to have... :-)
