I am 20 days late on my period.. I got tests day after when my period was due and it was negative. Took another 5 days and then 10 days late and was negative. Took one today and there was a faintest line, (don’t know how to attach photo) the control line was really dark so surely the test line should be dark too? I feel like I am so stressed I am seeing things now. If I was pregnant I would be 6 weeks ish I believe counting when the last time it happened..
