Spotting??

Brianna

So my period is due In almost a week and ive recently had protected sex (like 3-4 days ago) and now ive noticed what i assume is spotting. Its like really light blood almost a pinkish color. I usually bleed the same day or a day after sex but I have never had spotting this close before a period and i was just kind of worried and i want to know what this means. I doubt that i can be pregnant and i really hoping that im not.

It has been two days now and still the same pinkish blood when i wipe. Should there be anything i should look out for?
