Missed period

Hi ladies,  My menses is currently late by a week and it's still not here yet. Pregnancy test indicated negative, no sign of pregnancy symptoms too. Only white creamy discharge. The thing was that I had 4days of spotting(pinkish/browish discharge) two weeks before my menses is scheduled to come. Not sure if that is consider my 2nd period within a same month.  I have been ttc since earlier of this year. Have been taking blackmores folate for the past few months and just start blackmores conceive well today. Has everyone been through what I have been through? Seeking advices:)
