such a scare

M
7W1D earlier this evening I started bleeding and passed a nice size blood clot. I was so scared it was my baby. I had some cramps, ( to be honest period cramps are worse) Every time I went to the bathroom I had blood. 
Finally I got the courage to use my Fetal Doppler. AND WE HEARD A HEART BEAT. we are so happy. 
Anyone else experience this? 
Love to all
