Has anyone been through this ?

So I haven’t had my period this month I took and at home test it was negative and I went to my obgyn today she stayed that I tested negative for a urine sample however she wants me to wait and see if I have my period by next month because if not I’m definitely pregnant she stated there is a strong possibility that I am 5 weeks and my hormones aren’t there yet but I have been feeling sick and very weak lately ... has anyone been through this and what was the out come
