Hello beautiful group. I had surgery due to a septate uterus April 28th after the surgery I was for 30 days on Estradiol and 5 days progesterone and then got a heavy period/bleeding June 6th. For the last past 4 days Ive had extremely EXTREMELY sore breast and the day before yesterday I had a brown discharge when I wiped and then very very light pink when I wiped after using the restroom with some cramping that didnt last long. This morning my boobs were so so heavy that I decided to take a pregnancy test and it came back positive. I am so scared because I dont even know when I ovulate or how so soon is showing already. Please any opinions would help
