Random bleeding?

4 days ago me and my Fiance had sex. Right after sex I stated bleed. Not to heavy but enough for a pad. I was bleed the rest of the day mainly just spotting. Then next day I was bleeding also very lightly. I stopped that night.Today I woke up and when I wiped after I peed there was some blood so I out a pad on 2 hour after I got to work I went pee to see if I was bleeding more or started my period well the pad barely had any blood on it and I'm not bleeding anymore. Is this normal? My period is about 2 days away. But IV basically been bleeding very lightly on and off for the last 4 days.
