Is this possible?

Hey guys I need some help. I have been spotting since last week Friday. Comes out brownish on some says and pinkish on other days. Only when I pee and wipe. Sometimes during the day nothing comes out. It will come in the mornings when i wake up to pee and getting to the evening when I go and pee. I was supposed to have my period on Saturday.

Am so confused and worried. Menses hasnt come yet. It's just the spotting. Am also really scared to test cos I dont want to be disappointed. Has this happened to anyone here
