is it possible?

so i was having pregnancy symptoms for a couple of weeks before i got my “period” which was weird because i had so symptoms which i usually have bad cramping a couple days before and during my period. this time i didn’t cramp before or even that much during the “period” it was kind of light/medium flow and i could only see it on my underwear/pad and the toilet paper. it’s still here for the 4th day. is it possible for this to happen and i am pregnant? i also have a health condition ( something like crohn’s disease) idk can someone give me advice? i have an appointment to take a test monday morning. i just want to know what to expect and don’t want to get my hopes up if i’m not.
