Noticed something different (tmi)

Hey ladies.

When I was getting changed tonight I noticed something different about my boobs. I have bumps appearing over my nipples,around the edge is slightly a different tone, didn't have them before, has anyone else had this and what could this mean,

Also laid in bed my stomach feels like a balloon, got a headache, feeling tired, have had a headache, thirsty,pelvic ache and stomach cramping.
