BFN on pregnancy test, could I still be pregnant?

well since you tested with late night and forced urine that may be diluted i would say you still have a chance. also with this pregnancy i didn't get a light positive until my period was 4 days late. and it was really light. it took another 3-4 days before i got a real strong positive. You should test with first morning urine and if its still negative tomorrow then wait a few days. if its still negative or you get your period then there's always next month. took me 6 months to get pregnant this time around. also some women bleed during there pregnancy so you could still be pregnant.good luck.
