Need some help please..

My periods are regular. We are trying to conceive but I decided to take this month off of testing with opk’s and not stress about it, however this past week I have been super tired, crampy, cranky. This morning when i woke up I wiped and there was nothing.. this afternoon I wiped and I had some older blood (spotting) on the toilet paper... my period is not due for 9 more days but I’m very regular. Could I have ovulated early? Or am I just over thinking everything and it’s AF.
