How early did your boobs hurt?!

[Sparkesx]

I have sore boobs randomly, not even slightly very sore! I have started to track my periods and began OPKing. My fertile window started on the 4th (according to glow app) and I have had positive OPK's for the last three days but seem to be getting stronger?

I never get sore boobs, not even when i'm ovulating/near my period.

Is it possible to be pregnant or is there another explanation?

Last pregnancy they were very tender from day of ovulation, had never ever experienced sore breasts at all before this! Since having DS they would become a little tender a few days before AF. This pregnancy they were a little tender a few days before AF was due again, and got properly sore the day AF was due (14dpo) and only just starting to subside now (6+2)
