Your mare does seem absolutely adorable and I would love to see better pictures, we can overlook the baby belly!

I learned the hard way on how difficult carrying and birthing foals can be on a mare. My favorite mare is now swaybacked and looks like she's had 20 foals instead of 3!image I love her to pieces and don't regret breeding her (got 3 very nice foals from her) but it's always a risk. Enjoy your mare, have fun and ride her. Sounds like she's your best friend and I would cherish that
