I cant get pregnant and dont know why!

Hello! I have been trying tc a year ago and have done ALL my blood works to make sure I am okay as far as health. All my blood work came back great, did my ultrasounds to see my uterus and its fine! My husband did his sperm count and he is the way it should be. I have been doing OVULATION kits for over 5 months now. This last month I used CLEAR BLUE the digital since it was easier to read and it said I had ovulated on my cycle day 22nd and I had intercourse a week before it even said HIGH FERTILITY OR PEAK and I got my period yesterday! I dont know what else to do :( I already schedule a gynecologist appointment again :( ..

any other suggestions?
