I always try and wait till missed AF (never do) but sore boobs and extreme tiredness, made me test early. Yesterday I was 9dpo and convinced there was a hint of a line. My husband said there was nothing there and I was imaging it because we’ve tried for so long. This morning (10dpo) I think I have a line. It showed up after about 1 minute and seemed to get stronger. It is more obvious in person but still one of the faintest I’ve ever seen. What do you think?
