I have swapped from the injection to the pill (cerezette) about five weeks ago. I was on the injection from june last year, and havent had a period since. Ive just started my second pack of four, and i am on the second week. Recently, i ve been getting like occasional spotting of brown discharge/blood. A very small amount, it started on saturday last week and came back this saturday, not even enough to wear a sanitary towel. I m 17 and in a sexual relationship, but this one only. I ve googled my symptoms and the internet just say its a really light period.
