3 days ago I took a test and it came back negative, within 5 mins there was a little pink but the went away. (May have been faulty) then last night I had spotting but only when I wiped (6 days before af), woke up today and nothing? Thinking it was implatation, when should I test??? I don't want to get my hopes up we have been trying for 6 months. What do you think, implatation or not?
