I went on the mini pill 3 weeks ago, and within days of taking it, I got a very heavy period, associated with period pain and back ache. I also felt very nauseas. I put it down to the pill, and stopped taking it, and everything cleared up within 48 hours. I didn't know if it was a coincidence or if it was the pill, so I went to the doctor and he gave me a prescription for another pill. I'm worried about taking it as the period pain was awful and the bleeding was very heavy. I've never experienced heavy periods or even period pain before.
Are there other alternatives to the mini pill? I'm not keen on getting pregnant any time soon, and looking for some protection for at least the next 18 months.
