I have been trying to conceive since October and last month my period was late by 6 days which my entire life I have been very regular.... this month I’m late by 8 days and I feel nauseated every morning and I’m the middle of the night and I took a test and it was negative! What is going on!? Am I testing too soon because my menstraul cycle is longer all of a sudden and maybe my ovulation day is not 14 days after first day of period? Am I not pregnant and there is something going on with my uterus that’s causing irregular periods all of a sudden? Please help!
