I had a chemical pregnancy last month and my cycle is all out of whack. I have no idea when I ovulated as I took a break this month (was fed up). Took these over the weekend as my boobs are covered in veins and Ive been falling alseep as soon as I get home from work for the last week. Starting to get excited (!!!) but will keep testing for a few days because of what happened last month however...the line is much darker this month! Whoo hoo!!!!!
