Ovulation/Implantation

Hey 👋🏼 I’m currently on Cycle Day 35. My LMP was October 15th. I tested positive on CD 14 AND CD 20. Anyone else have this happen? I’ve gone months without having my period to having one the last 3 months. They’ve been somewhat normal, but my last was exactly how it should’ve been. I’m obviously out for my 1st positive ovulation, but when do you think I should test going off CD 20’s test? I had light cramping and back ache and really thought I was gonna start af on CD 29 & 30. I had clear and stretchy CM CD 29 (wasn’t ovulating) and CD 30 I had the same in the morning but the evening I had thick and cloudy CM. I also had a headache. But then it was all gone. So I’m sooo confused as to what’s going on with my body!! I tested tonight like a dummy because I was curious and it was negative. Gonna retest in the morning when it’s most accurate. Has anyone has anything similar happen and get their BFP??
