I took a first response test 10dpo, negative. Tested again 13dpo (yesterday) again negative, but when I looked at the test about an hour later there was a v v v faint pink line visible if I held it up to the light. Got quite excited so tested again following morning (14dpo)- nothing showing on the 3 minutes but the same pale pink line showed within about an hour, but still v v pale- no change from yesterday. I randomly found the test I'd done at 11dpo, and that one is stark white. AF due today but no show yet. I know I should really just wait a few days and re test if still no AF. But it's so so hard to wait and not obsess about it constantly! Has anyone ever had anything similar with a pale line showing hours later? Thanks!
