Hi. I started using the ortho evra bc patch two months ago, but it fell off early and i am having nausea with some vomiting all day every day for the past 2 weeks, tender, swollen, hot, painful breasts, serious fatigue sleeping 18-22 hours a day, lower back pain, cramping, and slight spotting. Do you think this is due to the birth control or do you think it may be a pregnancy?
