My cycle has been normal 27-28 days, I had one random that was 42 and my DR said not to put much thought into it that once a year a women has a random one. Than the one fallowing was back to 27 days, iv have just been going w a 30 day cycle give or take I'm 4 days late but test came back negative. Could I still be pregnant? I feel calm but kinda anxious for the yes or no
