Yes, I did put 18th - if I type first day of last period into the Babycentre website it gives me due date of 18th, but with the NHS one it allows you to adjust for cycle length and that one gives me 28th!
My lines are very faint still, and I had a chemical last month - so hoping it can't happen twice in a row! Came off Cerazette 5 months ago, don't know if that's something to do with it.
Anyway, got FMU stored in a cup and going to test again today with DH for proof of a line support 
Congrats baby!!!!!!!!

And good luck Ginger - we're holding our breaths!
