I missed a couple BC pills my last cycle. I missed a few during my fertile week. My period is due Monday but I noticed my boobs are getting this weird tingling feeling and my nipples are darker, and my boobs feel a lot fuller. Feeling a bit nauseous as well. Usually  before my period I don't get these symptoms. Does any one have any experience missing their birth control and getting pregnant? I don't know if these are just PMS symptoms.
