Hi I have been TTC for 2 months now, this is 3rd, have got horribly sucked in to early testing. Today I did a clearblue early detection (4 days pre period) was negative and then I left it in kitchen and went back to it and there was a line - I'd also opened it to look at the strip - it looks quite clearly positive now. Am I clutching at straws? Did another a few hours later and the same again - evap lines? Thanks in advance x
