Nine weeks spotting

Patient: I am 9 weeks today and have been bleeding on and off for three days. It initially was very very dark but is starting to get lighter. I have some tightness in the side of abdomen but it doesnt feel like cramping. I just went to the washroom and there are now clots coming out. I went to a walk in clinic and he checked my cervix and it is closed. I am trying not to get too upset and think of the worst but that is difficult. What is normal spotting and what isn’t??
