SMP: False Negatives?

Hey guys, just curious if taking an HPT on approximately the 25-30th day after ovulation could give possible false negatives if you took a single glass of water before taking it around 1 hour before the test.

Note: Second Morning Pee was used during the test and the color of the pee was yellow.

Thanks a lot. :D

After ovulation,you would no matter what get your period within 16 days,this is called a luteal phase,its impossible to be longer.so I would say you havent ovulated.if you had and were indeed pregnant,the test would have been positive by now.there can be many reasons for not ovulating,you may have a hormonal problem,maybe worth speaking with your doctor.
