I have absolutely tormented myself this cycle thinking I might be lucky this month... did a test this morning at 12DPO and the strangest thing happened, I got a faint positive line on the test strip, I literally couldn't believe my eyes. But I shouted my husband and by the time he got there it had faded away and only the control line was there. I've never had this before and use those strips all the time. Anyone else had that??
