Feeling confused

Emma

Hi everyone. I need some help on something that happened. Last sunday so 8days ago I had a clear blue digital opk read positive. Yesterday I started having sharp cramps on my left ovary side. Today out of curiosity I did another opk and it came up as peak fertility again. Also Ive been doing them everyday to make sure theyre not bad or anything. Now today most of the cramping went away and I noticed a super light brownish creamy color spotting. Does anyone know what this could be? Why did I get another peak ovulation at 8dpo? I saw online if the body failed to ovulate the first time it will try again, so I was wondering if that could be it.
