When can I test?

Hey y’all my last period started March 26th. My boyfriend and I saw each other on 2nd, 3rd, 9th, and the 10th of this month. According to the app I was supposed to ovulate on the 8th. I felt and saw signs between the 4th and 6th. I also took an ovulation test on the 8th and it was negative like you could barely see the second line. I also had some cramping and was more wet down there the 4th through the 6th. Then on the 7th I went to the bathroom and saw a tiny bit of bright red blood then wiped again and saw pink discharge. I’ve been cramping since then and my body has been aching a bit since Wednesday. Also I have never gotten pink discharge any time unless I was about to get my period so that’s not a normal thing for me
