Mid cycle bleeding

Hi my last period was from the 30th nov to 5th December. Me and my boyfriend had a tiny bit of unprotected teasing and protected sex on the last day the 5th because the flow was little to none. On the 13th I noticed a pink sort of light spotting when I wiped and it has continued for the past 2 days and today had some red clotty bits. I’m due to be in my ovulation phase now or soon and I was just wondering if it’s some sort of ovulation bleeding or could it be implantation I’m just not sure. Thank you to anyone that could help.
