So I bled the 28 and 29th, my peak day for ovulation was TODAY. June 7th. But I started spotting this morning and now I’m medium bleeding. It isn’t heavy but it isn’t light like spotting either. I don’t understand because I bled the 28 and 29 reallllly heavy which I thought was a period and I took a ovulation test this morning around 7 am and I was Peak, and 2 big lines. I started spotting around noon time, and then I bled all day medium. Please can someone tell me why? Was it implantation bleeding today maybe? I took a test on the 26th of May, two days before I had my period. I know that my periods are off a lot, but I’m just looking for help or an explanation thanks
