I’m officially 7 days late for me period . I’ve took two test. I took one when I was two days late and it was negative and I took one on my 6th day and it was still negative. I have been having cramps for like a week now, on and off and it makes me think I’m about to start but I still never do. Could I be pregnant and my hcg levels just isn’t high enough yet or could it be something else ?
