Hello everyone! I have a question....I was on the Orthro Evra Patch BC and I am due to change the patch every Monday. I took the patch off on a Thursday had sex, then on sunday I started spotting pinkish blood and cramping, and bleeding picked up a lil to a red color but its not a whole lot like a normal period. Along with that I have been nauseated, tired, n back pain. Can I possibly be preggers?
