I've been on birth control pills for about 4 years now...first 2 were Ortho Tri-cyclen then the last two they switched me over to the Ortho Tri-cyclen lo. Since Ive been taking them for so long, I know my cycles very well and have always gotten my period on wed of my placebo. Regardless if I ever skipped a pill, I never experianced break through bleeding. I still have a week left until my placebos and noticed some spotting today with cramping. Im confused and worried because Ive been on the pill for so long now and have never experianced this before. I know some people "spot" however I have never. Is there any chance I may be pregnant??? God I hope not! If anyone knows, please respond! Thanx!
