breast tenderness in just one boob !

hey there( im 16 month post op vsg, ttc starting current cycle) , last month was our first try post op and since 4 years , havent used any birth control since then , my cycles are clock work , when i got pregnant with DD i got tender veiny breasts a week after Ovulation, today im 9dpo and yesterday i realized my left boob ONLY was very tender to touch (tenderness focused in the midle are around the nipple ) i get pms tenderness but never gets too tender ... but i havent noticed any veins. did anyone get tenderness in just one breast ????and got bfp??

Only my right boob is real sore right now and I got multiple positive tests yesterday... so yes it is possible. Also, I am extremely bloated already to the point that my pants are tiiiiight. I am 4w1d only.
