*TMI PICS* Sign of miscarriage?

Betty
My sister in law is pregnant, only about 5 weeks. She got pregnant fast, her first child is only 3 months old. She keeps wiping to blood and there were some clots in it today as well as you could see in the toilet pic. Just wanted to get some opinions for her until she sees the doctor. Sign of miscarriage or normal? Side note she never had spotting with her first..
