Itchy nipples

Tessa.🌻 • I`m 23. Married to my bestfriend. Mommy to a beautiful little girl with baby girl #2 on the way.💕💜
I'm 6DPO and my nipples have been itching like crazy since I woke up at 5 this morning. I looked at them, they're not dry or cracked. Just super itchy. Could this be an early pregnancy sign, orrrrr?
