7-10 dpo, can you please share your thoughts?

My lmp was March 30th to June 3rd, af is always 28 days apart, according to ovulation calculator I should of ovulated on the 13th, I had the egg white cm on the 9th, which makes me think I ovulated early this month. So today I could be anywhere between 7-10 dpo. I usually get sore breasts a day or 2 before my period (which isn't due until the 27th) but a few days ago I noticed that the weight of my bed sheet was to much for my sensitive nipples. Today it seems as the whole breasts are hurting, but nipples are still very sensitive. I haven't been under any unusual stress, or anything like that, my fiance and I baby danced the 9th, 10th, and 11th. Does this make any sense having these symptoms so early? What are your thoughts on this? Thank you so much!
