I posted last night and in July (under a different user name) so apologies if this is a drag. I had three positive tests in July that then swiftly turned negative. I am now nearly a week late, and had a negative test on a digital last night (after having been to the gym and drinking lots of water), and then did another this evening (a tesco cheapy) and nothing came up, not even a control line. Anyone got any ideas or any advice?
