I had take the depo provera shot in October as a birth control measure after consulting with a gayenec. After a fortnight of which my period started and didn't stop. November. December. Late December I visited the gayenec and she prescribed Primolut N 30 in a descending dosage per day for a month. Ten days into the course my period stops. And starts again next week. This, the doctor said should be normal. The period lasts for a week. A week goes by. I got my period again. I thought it would take a few periods to normalize so I wasn't worried. This lasted a week as well. A week goes by and the period is back and this time it lasts 3 weeks. I need to fix this.
