Bleeding and HCG level check

Yesterday I wiped and had some brownish blood on the toilet paper, had some cramping all weekend, was feeling very nauseated yesterday and today... took a shower and found a blood clot the size of a chocolate chip and a small stringy one... going in to get HCG level checked, according to my LMP I’m 7 weeks which really I thk I’m more like 5 weeks since I ovulated and conceived 2 weeks after my period... just curious what a normal HCG level for both 5 weeks and 7 weeks is??
