sore boobs at 6dpo?

Megan
6dpo trying for baby 2 and still breastfeeding my toddler. I have had some weird light nausea the past two days and today my nipples are so tender! They are never sore (breastfeeding has toughened them up I'm sure), but today they are like fire! That was my first symptom with my daughter and got my BFP at 9dpo. The waiting is so hard!!! Anyone else have symptoms this early and get a BFP?
