TMI- Should I contact my doctor? TMI

I had an HSG last month. The infertility doc had high hopes we would conceive. I had a faint line for one day and chalked it up to an evap. But then I passed this. It's clearly tissue. I must have had a chemical pregnancy? 
I've had four early miscarriages and haven't passed anything quite this big.... 
Should I contact my doctor?
