Good luck to both of you. With my IVF and FET I had some breast tenderness and sometimes felt that they are swollen as my bra would be tight.
I had my transfer on the 10th and my breasts have been sore & enlarged....this could be a sign of the progesterone or early pregnancy or both!...(I read progesterone side effects & estradiol if you are on that too...they both cause breast tenderness)....good luck. I test in 2 days
