Weird ...

So I’m cd 24 of a normal 24-26 day cycle.. I thought my period was starting today - I went to the toilet and when I wiped there was blood - not a lot but enough for me to think it was af. Well since then today I haven’t had a speck of blood .. Like no where in sight..

Is this the start of af or could it be late IB? I honestly don’t know what to think at this point... maybe it’ll kick back up tomorrow...
