Pregnant? Please read and help me

I need help. I had to stop taking bc in October cause I got a blood clot from it.I had spotting November 3,4 and 5th. Then on November 6th I got my period. On November 15th my boyfriend stuck it in once with no condom. I tracked my cervical fluid and think I ovulated on November 24th. On glow it says my period will start dec 4th and my other app says dec 7th.The past three or four days iv had light cramping. Iv noticed a couple new pimples. My boobs are not sore.Tonight I stared getting Very light brown discharge when I wipe. Also my cm is stretchy but DRY as if I was fertile but I don't get how it is. The past couple of days I was white and creamy.Could I be pregnant? Or is this my period?
