trying to have a baby

I've been sort of trying to have a baby for about 6 months now, but this month I'm REALLY trying, I just got off my period yesterday, I've been taking first response reproductive health vitamins to help me get pregnant for the past 4/5 days now, I started ovulation testing today with the clear blue advanced tests sadly it came back negative, I also have pre seed for when it says I am ovulating that way I can up my chances! Anything I should try to help?
