Pregnancy

Hi everyone. I’ve been together with my husband for over 3 years. He has no kids but I have 1 child who is 11 years old which my husband love to death. It’s been a few days since I ovulated. Lately I’ve been experiencing mild cramping on my lower left abdominal. The cramping been there for 2 days, frequently urinating. My period is due and in September so therefore I don’t want to test until I’m due for period. Can that be ovulated cramping? I really don’t want to put my hopes high. We have been trying for so long and nothing has happened yet.
