Cycle confusion..

So my estimated ovulation peak was 25th Feb. I had high bbt, a few symptoms & i had high fertility (but never got a peak result). It dropped to low for a day then returned to high fertility last Saturday. I'm now apparently in another high fertility but I've started feeling off (nauseous, a bit of a hot flush, sore boobs & I had some intense cramping/light stabbing pain in my lower left abdomen late last night).

When so I classify that I ovulated? I'm very confused lol! 🤦‍♀️
