Yesterday I was 11dpo and started spotting. Wasn't expecting it at all. I started bleeding properly today. Af wasn't due until the 22nd (14dpo) I've been tracking for the last 4 months as I'm ttc and ive never started early. Ive been getting positive opks on cd 18 every month so I don't think it's because I ovulated early. Is this normal or could there be something wrong with me? I've been worried about not conceiving as I got pregnant so quick with my son and this has made it 10x worse..
