I'm DESPERATE for opinions!

Helpless.....that is what I'm feeling. TTC #1 for 8 months, i have been to the doctor (not much help, cause we haven't been trying "long enough") had full blood work done, all my female hormones were normal.... Did ovulation predictor for 2 months, never caught a positive. and I am in desperate need of help to understand...WHEN I ovulate, IF I ovulate, and if I do ovulate WHETHER it is a long enough luteal phase? Please give me your opinions, I have researched over and over and I still don't understand what my body is doing!

Ps. My current conclusion is either I ovulate the last days of,or day after my period, or I don't ovulate at all :( Thank you so much for any and all feedback!
