Please help

Ashlyn
To start at the beginning, I'm on micronor for BC I missed 2 days by mistake. A couple of days ago I started spotting (AF isn't suppose to be here for another 2 weeks) my boobs are extremely sore, more than usual, they kinda just feel full if that makes since and they're heavier causing my back to hurt. On top of them being sore they itch like crazy! Around the sides, the bottom and the nipples of just my left boob. 
Now, I've been known to over react to things like this... So maybe I'm just over reacting again. But these are all pregnancy symptoms. So, I guess my question is, do I need to take a PT or am I over reacting? 
Thanks for the help!
