Strange period

Kimmie
My husband and I are ttc and my period was late a few days. I took a test it was negative. My husband said maybe I was stressing out causing my period to be late and it wasnt pregnancy at all. When my period did come it was very heavy the first day, with small, medium sized clots/tissue. The second day it was still heavy buy mostly gushy, no clots. The third day (today) I spotted a few drops this morning in my pad and I have been dry the rest of the day. Which is unusual. My periods always run at least a full 5 days. And I have had really heavy periods before but it progressively got lighter not just stopped. Its odd im not sure whats happening to my body right now. Do you think maybe its a miscarry?
