I came off the pill a year ago. I was on it for a year. Since coming off it, my periods have been much shorter than they used to be. Before I went on the pill, they were five days. Now, they are only three days. I'm worried this means something is wrong, cos when I read up on the pill, it said that one of the ways it stops you getting pregnant is by making the lining of your womb too thin for an egg to implant. But i would have thought that after a year, I'd be back to normal? I haven't been ttc for a year. Just five months.
