why two months in a row tho?

so my last two cycles I've had brown discharge last time it was for a day and a half and today I started having the discharge again Idk how long this will last. last month two days before my "period" came my boyfriend came in me and then I noticed that brown discharge the two days after I have felt tired lately and feeling nauseous but I'm not trying to symptom spot. has anyone had this before and it's normal or could my eggo be preggo?
