Am i Pregnant ? Is this normal ?

Okay hi guys .. so me and my my boyfriend just had sex this week . My period was last week . Today is Friday . It’s sex Tuesday & Thursday... I’m experiencing some light pink with a mix of discharge , only when i wipe . The sex me and my boyfriend had was quite rough as other times i have had some tearing which caused soreness at one point ... but right now ... is my concern .. could i be experiencing implanting or is it just that my boyfriend maybe was too rough and maybe shook some things around in me ... hurry with response please .
