So confused!

So me and my hubby have been TTC for a little over a month now, I have super irregular periods but I had my last period Jan 17-22 we had sex jan31 and that next day feb 1 my ovary was aching so bad and I was super bloated which i thought was a coincidence, I use two apps and according to my other one I wasn’t ovulating until feb 7-18 though. But on this app it says March for ovulation. the last week or so though I’ve had mild cramps,bloating, super irritated and hot flashes. Could it be possible signs of early pregnancy? Or am i reading into it too much. Period is suppose to come within the next week but it’s never accurately on time.
