Could I be pregnant from having sex on my non-fertile days!?

Okay so I'm feeling weird about this and wanted to get some opinions. This morning when I went to the bathroom I noticed I had heavy EWCM which makes sense today is my peak day for fertility! However when I wiped this morning also I had one dot of blood and it was bright it caught my eye. I haven't had any since this morning and I'm not supposed to start until the end of the month? Could I be pregnant? Would it be too soon to test? I added my calendar so y'all could see where I'm coming from. I'm super confused.
