Needing help please

I'm definitely needing a little advice ladies . Day 9 post ovulation I had a sharp pain almost like a pinch on my left side near my ovary. Now I'm on Day 10 and I have lower back pain and cramps and sensitive nipples I also have a headache and am a little tired . My period comes in 6 days but I usually don't get cramps this early and I don't ever have a sharp pinching pain . I looked it up and for some ladies that's a good thing and that means implantation. Has anyone ever experienced anything like this before ? And if so how long did you wait to take a pregnancy test? Really needing some positivity
