Ovulation bleeding

Sara

I got my period about over a week ago and I’m in my first day of ovulation and I’m bleeding as if I have my period. It’s medium flow and I’m super confused as to what this is. This is the second time it’s happened. I feel absolutely fine and I’m an athlete also. I took a plan b about 3-5 weeks ago and everything was fine after that then the irregular period occurrences started happening. I don’t know if it’s that but it’s been a while. Please what is it????
