I think it's really REALLY time to stop testing and find out what is up with all of this off and on spotting. The "disappearing positive" just looks like the antibody strip showed up as the dye moves across the test field and the accuclear does not appear positive either because the entire test filed is still pink. Unless there is a pink line in the field that is
darker than the rest of the field it doesn't mean anything to have a visible line with pink to it. What did the test look like at the time it says to read it? The reason that tests are supposed to be read at a certain time is to give the test field a chance to clear so it will be easy to see if the test line is pink against the white background. A positive will only get darker, not lighter, as the test waits so there is no reason to rush to read it. I am so sorry that you are getting bounced around so much with this, hun but I really think you could save yourself a little bit of the heartache if you would stick to good pink dye tests (I think accuclear are horrible just from your evaps), read the tests at the time limit and then scratch the field and throw it away.

Stress can delay ovulation and it's no good in pregnancy either.
