Is this normal or should I see a doctor???

Hey ladies. First off a little heads up this may be TMI. But I’m 7 months pregnant and with my first so I’m not sure if this is a normal pregnancy thing or if it’s something to get checked out cause i definitely scared myself and shouldn’t have looked it up on google cause it said breast cancer soo let’s hope this is normal. But my left nipple has been itching like crazy, and I’ve been having discharge which I know that’s normal because milk duh, but I noticed earlier today that there was blood coming from my nipple while it was insanely itchy. Should I be worried!?
