I have been on the pill for about 18 months before that I had the coil fitted and then removed , with my pill I took it straight through without a break because of endometroisis now I have had my endo treated and the doctor has said for me to start having a break in between packs of pills again and to start having periods well this is my first break and no period has arrived does anyone know if this is common . I just keep hoping it is because it takes a while for my body to udjust again I am just praying it isnt because I amm pregnant
