I would say it would be due to the pills if you have not been feeling this way for a month now. It may have been that the old BCP's were not working well for you. But starting the new Orthro on Sunday is a bit to early to feel symptoms of those pills like that. I would highly suggest having a blood test to confirm if you are or are not pregnant at this point, especially with it being a month and the spotting. It may be hormonal from the Old BC not working perhaps, but just to rule out, please do a pregnancy test. Other wise, if the blood test comes back Neg- for pregnancy, then wait a month and see how you feel on these new pills. (If the hormones were not enough or too strong--then it can cause havoc on your body) but do try to get in tomorrow to see about a blood test.
