New symptoms...

So this month (10 months ago I had my daughter, 11months on August 14th) and this month my period has yet to show up, it's not technically late since today is the day it's supposed to show. I had some cramping yesterday so I expected my period today, but today my boobs literally feel like they did when I was breastfeeding my daughter. When I needed to feed her or pump, I'm getting the shooting pains and pressure like if I was engorged. It's awful they are so sensitive to touch. My husband and I are using the withdrawal method so I know it's not impossible to get pregnant, but I also know I have surgery on August 11th for my ankle, I have a talofibular ligament tear they need to fix. Last night I wanted a PB&j and Doritos and today I wanted taco meat with Mac and cheese. I know these can all be symptoms of both period and pregnancy. I guess I just need to talk to someone before I drive myself crazy.
