Another who hasn't posted in absolutely AGES. Third thread already, that's pretty impressive! I'll have a read through if I get the chance...
I think we got to two cycles of properly trying, having had all sorts from illness to bereavement to the bloody cat not coming home one night putting the kibosh on it all. I was convinced my fanny was broken (dramatic? Moi?) and bought myself a pregnancy test and a load of biscuits to cheer myself up when I had another BFN. It was only blimmin' positive wasn't it?
So 4+2 according to dates and just filling time until that magical 12 weeks when it's fine 
Congratulations to all the other positives, you must be thrilled!
