No period since august and 4 negative test results help!!

I'm just wondering if anyone else is experiencing the same symptoms as I am as I am getting a little concerened.

My last period was at the end of August. I have done 4 tests and all have come back negative... I thought I came on yesterday as I was bleeding but today there is nothing and I'm very confused lol.

I have made an appointment with my nurse but I have to wait a week to see her so i was just asking so I could get an idea of what is going on in the meantime.

Any advice would be greatly appreciated x x
