Confused (Maybe TMI)

Hi all, I am so confused. From my chart I had my period end on the 4th of Feb. When I was ovulating I had (tmi) bleeding for 9 or more days but it was just here and there not all the time. I started getting emcm and have almost bd every other day. Based on when the ewcm was heavy today should be 14dpo. I have had cramps some mild some a bit worse (to the point it felt like Aunt Flo was on her way). I have felt nauseous but not sure if that was down to feeling too full after food. I have been feeling fatigued. I don't want to test and have Aunt Flo right away afterwards. How long do you think I should give it before I test? Any thought would.be appreciated. Thank you.
