Need some help please. . didn't start yesterday

Jessica • I`m a mother of 4, ranging from 6 to 15yrs old. I was married for 15 yrs to their father...I`m finally happy and My boyfriend and I have been together a year now.
Ok I was suppose to start yesterday and didn't. . I had cramps and all the period signs yesterday but no spotting or anything yet. I had my iud out 3 months ago. I took a pregnancy test day before I was supposed to start.. so what could this mean...can I be pregnant or probably no..any advice please would be grateful!!
