Been ttc for number 2 for a while now , these last few months I became obsessed ! Symptoms spot everything & the amount of money I've spent on pregnancy tests too 
I've put my body under too much pressure & decided to have a 'break' with it all.
Last night at work my hair was so greasy after washing it after a few hours and realised from then I was pregnant , test confirmed this morning !
I looked back and we dtd on the 26th and 3 days ago both out of my ovulation window.
Must of ovulated early this month as my cycle is normally 33 days.
