Took a pregnancy test a day before my period come it was negative but still no signs of my period??

Zheyan • I`ve been married for a year and trying to get pregnant. Never used birth control pills hoping to be pregnant soon!
According to the Glow calendar I was suppose to get my period today and I have not at all..granted sometimes my period is a couple of days late my husband thought we are pregnant! I took the pregnancy test last night it was negative ? I still don't have my period though?? Anyone experiencing this problem?
