Invalid OPK or did I miss my window??

Anne

Been testing twice a day, this morning I took the one labeled 11 am but barely got any pee on it because I didn’t have to go as bad as I thought (like half of the stick was still dry) so I assumed there wasn’t enough urine and tossed it away. I just went to take my 1 pm one and noticed the two dark lines on the 11 am one. Is this invalid or did I just miss my window??
