5 weeks 4 days pregnant. Two days ago my breast wereVERY sore . Literally overnight that decreased significantly...I woke up yesterday and they hardly hurt at all. Today still tender but not nearly what it was 2 days ago. I have never had a baby and am wondering if anyone else experienced this and it was okay? I don't have my first appointment until next week. I am also taking Progesterone b/c of 2 previous miscarriages. (my progesterone isn't low, Dr. just said it couldn't hurt and might help). Thanks for any input. I know you can't diagnose these things online but it's helpful to hear other's experiences. : )
