I'm not good at this lol

Alicia • Married with two little boys.
So lately my CM has been back and forth and confusing, and I've been putting out extra heat. My hands and feet are warm to the touch. Usually they're cold to the touch. I got a BFN on 9/30/15. I'm 8 months pp and EBF, no AF as of yet, so I don't know if I've even ovulated yet. Could this be early pregnancy, or ovulation? We're using withdrawal method, that's the only option we have right now (sensitive to condoms and can't use hormonal bc). I know there's a chance I could be pregnant, just want some input.
