Has anyone gotten a negative on the day of their missed period but gone onto get a positive later?

Hi there =) I have a regular 28 day cycle and have been ttc for the past 3 months. I feel hot, period like cramps, bloated and have like lotion like discharge and very tender . I was suppose to get my period today or yesterday but has not arrived i tested to days ago and it was negative. I still have a feeling i am still pregnant and i am going to take another test in a few days =) Good luck and heaps of baby dust for you =)
