Ebay pregnancy tests

[wantanother]

I have bought some but am wondering how acurate they are being that they are so cheap.
For the last week I have been feeling tired and sick af is due today but had a bfn from one of these am wondering if I should pay out for a clear blue.

And yes I know I should wait but am getting worried about why I have been feeling so yucky for the past week or so!

I have always ised ebay cheap tests and have had correct results when pos and neg. Usually when I get a pos I will then back it up with a clearblue but in the meantime they are accurate or always have been for me.
