OMG!!! For the past 2 days (since 6dpo) my nipples are SO painful and stingy. I have no idea if this is a good sign or not but this has never happened to me. My boobs aren't sore just my nipples. They're also very swollen and bigger than normal. I'm typing this in so much pain right now!!! Does anyone know is this could be an early pregnancy symptom? I don't have any other symptoms though unfortunately.
