I have been on birth control for 2 months now and my last period was 2 days late and very heavy for 1-2 days then it was gone. I haven't missed and pills and I take them at the same time everyday. My boyfriend and I don't use prtection and I have been having sickness throughout the day tender breast spotting after intercoarse tiredness emotional and like really bad back aches(WHY?) I took a test about a week ago and it said negative should I keep taking the pill or what? And if I'm not pregnant why am I having all of these symptoms should I change my because? Thanks

The pill does all og these things to you I'm afraid. It messes with your hormones and if you have only been on it for 2 months then this is most likley the cause. If you really are concerned then have a blood test done but to be honest the chances of getting pregnant on the pill (if you are taking it correctly) are very low and the chances of getting a false negative are also very low so the chances of both are extremely low.
