Feeling down

Cara

First time writing here. I took a test (actually 4) after two years of trying and they were all positive. The app said I was 7 weeks. Then I had to travel for work and go on a brutal trip across America and then overseas. Today I had super bad cramps and then found two huge clots when I went to the bathroom. (Sorry TMI). For the next couple hours it was bright red but getting lighter and lighter and now 6 hours later the blood is gone. Was that a miscarriage?
