So I'm one who has very irregular periods, but recently about 2 weeks ago I bled lightly for a week straight. I knew it wasn't the same as my period because I could just tell. Well I use clue to atleast help me try to figure out when my next period will be and usually it's right, but it's been two days and still no period. I took a test last night & was a dark negative. This morning I took one and a very faint negative. I also feel like I see a sliver of a line going downward. Am I crazy? Or could this be a positive?
