Ive been using regular opks and have been having issues with reading them (not sure if they are positive or not) i bought a clearblue fertility monitor for this reason.

i woke up this morning with cramps on my left side so i took a test and this is the darkest OPK ive ever gotten. Ive been using them since March. Then i tested again and my monitor definitely confirmed it. ....we already BD and used pre seed. If this isn't our month. Im going to start temping to confirm ovulation.
