IB or AF??

Okay so I was supposed to start my period on the first of January but got what I think was my period on the 27th which made me 12dpo it was lighter than normal and only lasted 3 days when it usually lasts 6 I have a pretty regular cycle too that comes with heavier bleeding and bad cramps but this time I had light cramps on day one and that was it and it ended yesterday and I haven’t had any bleeding from yesterday afternoon to tonight but I just wiped and had a tiny amount of light red blood when I wiped but. I did have unprotected sex from the 10th-25th and my boyfriend came inside me every time. I ovulated on the 15th so I’m wondering if you think it was AF or IB. Help!!! Picture from when I wiped
