I am six weeks pregnant and I take crinone twice daily and estrogen three times daily. When I go to the restroom, there is brown pieces in the toilet, looks like soft tissue. Never pink or bloody, but a brownish color. I have googled these symptoms and I'm getting a 50/50 answer, that I'm either fine or it's signs of a miscarriage

I'm getting a little worried. I don't have an ultrasound until Wednesday and in getting very scared ??? Anyone else have these symptoms before ?
