My fiancé and I have been trying to conceive for about 4 months. Well about 6 days ago my breasts started to get really sore. I've never had sore breasts before. Never before ovulation or before AF. For the past 2 days I've been exhausted and have lower back pain. I took a test today and got a bfn. AF isn't due for roughly 10 days. But the soreness is awful even at the lightest touch.

Any advise? Any one have sore breath as an early pregnancy symptom?
