Please help me understand

preggo w/ baby #2 • Mom to a beautiful 1 year old baby girl 10/11/18👛 and pregnant with baby #2 due 8/22/20. 1 miscarriage 12/8/17👼🏻

I’m not freaking out, but I am in need of guidance. Does my temps mean after ovulation that I more than likely did not conceive? I am asking because I know the temps should be high and mine are not even about eight he cover line. Please help educate me in this process... thanks ladies! Baby dust!
