Implantation bleeding or early period??

Jordan

I've been trying to get pregnant since March and have been tracking my fertility, I took a clearblue ovulation test Sunday 7/09 and it came back that I was at peak fertility so of course I was excited and my partner and I had sex a couple of times that day. So yesterday(exactly 7 days after) I got slight cramping and light spotting. It was off an on all day but last night it started to get a little heavier and more red. I've read that implantation bleeding is rarely red and very light spotting. My period isn't supposed to start until next week.

This is also my second pregnancy(I have a 2 year old daughter) and experienced no implantation bleeding. I'm just wondering if anyone has experienced a similar situation and it did result in pregnancy. Or maybe my period is just early. Any insight would be so helpful😊
