15 weeks pregnant and I have a red spot next to my nipple the size of my palm. No pain, no lump. Feels a little feverish. Help?!

See your OB. This sounds like a fairly large red spot on your breast if it is the size of your palm and without examining you it would be impossible to guess what is going on.Since you are pregnant the diagnostic possibilities are greater and your OB would be the best person to diagnose this. Hope this helps.
