Hey All .. I am on my 11 cycle day and I took a clear blue advance starting yester and I have low fertility however I took a lh test that I bought a bundle on amazon and it was negative this morning and postive this afternoon.. is it ok to ovulate so early and have I missed my window .. just confirming the below is in fact postive and would you trust a cheap test from clear blue so confused and upset that I missed my month once again.
