Super sore breasts?

Ladies, been TTC for a couple months after our first miscarriage. Super sore breasts (like on a scale of one to ten is say fifteen) and nauseous, also regular headaches and dizziness like last time. Haven't missed yet, tested negative the days ago because the tests I kept stocked were slowly driving me mad. So I know it was to early but in a few days my period should start so I'll know by next Monday. My question is this, mostly I'm only sore in one breast. Is that normal? Especially when that beat is slightly larger than the other? Anyone else notice this?
