It's 2 weeks since we last DTD, so i know that's when we conceived. I had EWCM 2 weeks 1 day ago. I'm normally on a 28-31 day cycle, so due AF no later than tomorrow. I tested 2 days ago and got a faint but definite positive. 2 days on, no different. It took 3 minutes to appear this morning. I had the same last year and miscarried at 6 weeks- the tests never got darker. The next cycle, they did get darker, then i miscarried after a slow heart rate. I'm so worried. Please tell me some of you didn't get a dark line until a while after you period was due?! I'm going to the GPs tomorrow to ask for a couple of blood tests for an HCG raise as I'm too anxious for all this malarky, to wait for another pregnancy to come to an abrupt end.
