D.L.
I too shed my hair after both my pregnancies, it started about 4 months after delivery, lost half my hair, had bold spots, then stoped about 3 or 4 months later. It is all hormonal (or was for me). Give it a few months, it should go away once your body has time to adjust. My thyroid was also affected, went to an endocrinologist, who told me it takes 2 full years for hormonal levels to go back to normal on their own. Sure enough, they did. I don't need treatment for my hypothyroidism, a it is now gone. it is hard to be patiente sometimes, but it's reassuring to know it's all sort of normal.
Good Luck!
