I have experienced cramping for the past three days, similar to menstral cramping, but there is no discharge. I'm also experiencing breast tenderness and muscle pain in my legs, arms, neck & shoulders.
The last day of my last period was October 30th and it is now December 5th. I've missed my cycle by an entire week. On the 31st of October I had unprotected sex, but took Plan B as soon as possible (the next morning).
Since then I have had sex, but always used a condom.
I've been under a lot of stress, moving out of my parent's house and fighting with my dad, and recreationally used cocaine. I haven't used in over two weeks and am planning to stay clean, but I'm still worried that I may be pregnant (or may have been).
