Hi, I took the generic version of plan b on July 9th and ended up not only getting a false positive pregnancy test but the side affects of pregnancy. Nausea, tender breasts, headaches, cramping and my anxiety and depression increased rapidly. I still haven t gotten my period either. I got an ultrasound done when I thought I was pregnant from being told by my gyno that I was and they found nothing, took more tests that day and they were negative as well. I ve read the morning after pill can have weird affects that lasts months could this be the case for me? I ve also been diagnosed with hypothyroidism for a few years now and thought it could ve been a drug interaction?
