Best time to take PT?

I had a few pregnancy symptoms a couple weeks ago, but then I started my period. They normally last 6-7 days every time and this time it only lasted maybe 3. It was super heavy the first day and then hardly anything after that. It's been a week since and I've been itchy and have tender breast and have been nauseous. I'm supposed to ovulate next week so should I test now or before my next period?
