Had sex a couple of times during my fertile window last week. At 7 DPO I was checking my cervical position and there was a tiiiny bit of blood on my finger afterwards, followed by some light pink CM when I wiped. It was accompanied by a day of mild cramps and a bit of a restless leg. Period not due for another week or so. I don't normally spot between periods. Is this implantation bleeding? I'll test next week.
