Help please

Hi my name is Kathryn & the last time I've had my period was September 25th, I have a boyfriend we've been together for a year & 7 months & we have always had protected sexn he is also my first. I do smoke marijuana but not frequently, & I also do have vaginal discharges & they are frequent but I've always had it, even before my boyfriend. Can someone please help me asap!! It would be much appreciated!!!
