idk what to do

im 17, and im 3 days late im scared but i know that i should wait like 4 more days to see if im actually pregnant. Someone told me to drink aspirins so my blood can be more liquid or something like that... I'm really really scared. I kind of feel this thing every time my period comes, like something is coming and i go to the bathroom and check, I felt it today but it hasn't come so im still scared and dont know what to think or do😣
