Advice please! Possible miscarriage...

Elizabeth

Hi there, my husband and I are TTC...I was supposed to start my period last Sunday. I started to spot a bit but never a full period. I took several test but they were all negative. My period finally started last night with horrible HORRIBLE cramps. Today I went to use the restroom and found this:

It is hard and not full of liquid. Any idea or been through this ? My doctor believe it might be an early miscarriage. As you can imagine I am heartbroken even if it is early...it hurts. Thanks for the help.
