I have a slightly irregular cycle (24-31 days but on average 26) and am currently on day 28 so my app is saying 2 days "late". We only DTD twice this cycle due to crappy shift patterns and DH travelling, and I think both times were after ovulation (although I never get EWCM so it's hard to know). Does this look like an evap line or a positive?? Its a Tesco test; positive is a + sign in the round window. I feel like I can see it but worried I'm imagining it because I want it to be there! Someone talk sense into me
