42 & 4 days late

Hello, I'm 42 & 4 days late with consistent periods. 1x late-that was with 6.5YO daughter. LONG TIME BF & I had surprising sex (on a Thurs. about 2am) b/c I was upset & tried not to. I began ovulating that Friday b/c boobs started hurting. Now I'm 4 days late with 3 negative tests but white discharge heavy off & on; sore boobs off & on; & nausea sometimes after eating & then sometimes just nauseous mostly in afternoons/night & then it passes; extremely constipated; bloated. Regular temp. been 99.+ & I'm cold natured but hot sometimes, sometimes cold feet? Any suggestions-whats going on???
