Post Ovulation Cramping & Pain on the Left Side?

I am CD 29. My typical cycle is 35 days. I ovulated on day 21 after taking Femara CD 3-7. After my ultrasound on day 12 I had 3 follicles measuring at 10 mm (was excited because on the last two rounds of Clomid I had no enlarged follicles).  I am in the TWW and am having some cramping and in the last couple days am having pain on the left side, what feels like my ovary. Is this normal? Does this mean anything? Has anyone had pain/cramping on one side like this? Wondering if it could be a pregnancy symptom or a side effect for Femara?
