Hi. I Got My Period On 12 Dec, And I

hi. i got my period on 12 dec, and i had sex like 7 times since then. eveytime with a condom and he didn t ejaculated in me. but last time, i mean yesterday, the condom broke but we figured that out right away and we stopped, even though he didn t ejaculated. Last month i had some brown discharge before period and then 3 4 days later, my period. i am experiencing the same brown discharge since 2 days ago and yesterday when i had sex blood was coming out. what s that? could i be pregnant?
