Hi, I'm currently taking Alysena 28. My periods are usually pretty regular for the most part and I have a medium-heavy flow. Now, I ended my last period on December 17th, 2013. During that week of my period, I missed two pills in a row (I think it was the 14th & 15th) but just continued taking one pill a day on the 16th as if nothing happened (I wasn't too sure what I was supposed to do). I then missed another pill around the 18th. During this time, I had had unprotected sex a few times. Now it's December 24th and I've been having some nausea, a lot of fatigue, headaches, no appetite, I've been peeing more frequently, mood swings and I think my boobs have grown. But when I pee, sometimes it burns very slightly and sometimes there's no burning at all. I'm not too sure what it going on but I keep thinking it's either pregnancy or a bladder infection since they have a lot of the same symptoms. What do you think it is?
