I don't know how long my cycle is as my periods have always been irregular (and December's is the first for 4 years!) but, based on my December one, I think I'm probably due on 23rd September. Good for the school year!
If the faint line has the test colour - blue or pink - you is up the duff! If just greyish and only visible in certain lights, you may not be (prob just an evaporation line). Try First Response if in doubt; I could never get conclusive results in early PG with bog standard tests.
I'm ttc for the first time. I came off the pill at the start of December and had a period at my 'usual' time, which was mid month.
I did a load of ovulation tests at New Year but none came out positive. It's possible I wasn't doing them correctly as I misunderstood the instructions
I am now ~ 5 days late for my period, although before I was on the pill I had massively irregular periods and had been referred to a gynae with suspected endometriosis. I cancelled my endoscopy because I'm a wuss I decided it was unnecessary surgery at that time.
Anyway, today I did a test but forgot to check on it after 10 minutes. When I came back to it after an hour or so, there was a very very faint line. I'm using these as they are cheap and easy.
Is the faint line just a chemical response post hours, or is it the start of a dark line? Will retest in the morning with first urine, but just wondered how reliable any form of line is!
