Negative HCG DPT 5 ovidrel. Please Help!!!

Rachel

I completed my femara dosage and had 20mm follicle. I had ovidrel shot on last Wednesday(02/21) and I took hcg test today(02/27) just to check if hcg is still in my system. I see negative hcg. Also noticed cervix position little lower than yesterday. Does this mean I am not pregnant this cycle?
