Hi, I ended my period on a friday and had unprotected sex with my boyfriend using the "pull out" method the following sunday. I took Plan B about 2-3 hours later because I was nervous about getting pregnant. It is now Saturday about a week later, and I have been getting cramps and blood which appeared on thursday or wednesday and ended friday night. Also I have some lower back pain and my areolas look a little different. I don't think I am pregnant since I was pretty proactive about the pill and I wasn't ovulating, so I am wondering if all of this is due to an imbalance of my hormones since Plan B is so strong - or if these really are pregnancy signs? And was the blood pregnancy spotting or my period? Thank you in advance.
