So confused!!

[LittleSienna]

So We are not actively ttc but not on any birth control, due to clotting risks. My LO is 3 months old and my OH didn't pull out on sunday like usual so obviously i know there was a risk there. But 4dpo I have started to bleed, I am so so confused what is this bleeding? My AF is not due for another 2 weeks, I ovulated on Saturday i think. Please someone help !

Some people spot in their luteal phase. Others might say implantation bleeding if you think its possible you had sex during your ovulation time?
