Pregnant?

I know you can’t tell me if I’m pregnant or not but I’d really like to hear your opinions or any information that could be helpful!

I had sex on last Monday, the 11th. My period was suppose to come 4 days later (Friday, the 15th) but right now it’s almost Tuesday, the 19th. I had very very light pink spotting when I wiped on Saturday and today. Usually my period isn’t really late, except maybe a day sometimes. Any opinions? (Hopefully I’ll be able to take a pregnancy test soon) And also, I used the day and date to try and make it easier for y’all to understand.
