I am 23 and I had my first child 6 months ago. My doctor told me that it would be best for me to go o the pill. I started taking it and I have noticed that my period wascoming on every two weeks, so I stoped taking the pill over two months ago ad I am still getting it more frequently. I am getting it oe week it goes away after 7 days and within a half week later I got it again can you give me an answer on why this might be happening
