Cramping? Spasms? What is going on?

Clara

So after my ovulation I'll feel this light little cramp or spasm where I would think my ovaries are. (Any stomach pains I've had are a bit higher and more central and these have been lower and on either side). These will happen for a short time almost every day and I'm now 7DPO. Anybody know if these are period cramps? Implantation signs? I typically dont cramp until my period starts and those are much stronger.
