I'm not pregnant!!

Haha!! I certainly shouldn't have been pregnant, but I was worried. I had my sterilization procedure done in September. I had a regular period in October, and just about 30 days later again in November. I was pretty certain I'd have another regular period around December 15th or so. Not the 15th. Or the 16th. Or the 19th. Not the 21st. Not even by Christmas! I was getting worried that somehow the surgery had failed and I had gotten pregnant. I've been off work since last weekend, and today was my first shift since last week. While I was there, I got my period!!! That is really not something I want to have to stress about...
