High FSH levels

Shiv80
Hi ladies,
I just had a copy of my day 3 blood work back and noticed everything is within the normal range except FSH which is 36 u/l although lab note underneath says normal menstruation! I have stupidly been googling this and get the idea that this is not good at all and getting myself on such an emotional mess! My ob/gyn appointment is not until 7th September so going to drive myself crazy with worry now. Has anyone else had a high FSH and can give me any advice before doctors appointment please?!
