Yes it’s normal, every women is different and our bodies respond differently. When I went through the pill procedure I cramped only a little bit at the beginning but then bled like I was dying. The bleeding was on and off but steady for a few weeks after.
If you’re genuinely concerned or feel like it may be something else I would get seen by a doctor.
I’ve never experienced anything like this as I had mine done at the hospital so it was a different procedure. If you are worried are you able to call them and explain? Xx
