Hey I'm 17 and have been on this particular pill for almost 3 months..(I have been on two other forms of contraceptive within a year and bit, first the pill, then changed to the needle then back to the pill) I had my period a little over a week ago, and since Tuesday I've had some very light spotting, it's been a brown colour and has hardly been red, I have regular unprotected sex and my boyfriend always ejaculates in side me, I've missed 3 pills in a 15 days, what could this mean?
