How quickly did you get sore breasts?

McKinley
Hello ladies!
So DH and I had unprotected sex my my last fertile day this month according to Glow. Ever since I went off birth control a year ago I haven't had ANY breast soreness accompany my periods. Two days ago I noticed my nipples were a bit sensitive and each day since then it has become increasingly worse. As of right now, I would say my breasts are only slightly sore (not painful), but it is definitely getting worse. My period is expected tomorrow and I am going to test. How quickly did it take for your breasts to get sore when you found out you were pregnant? Did it happen overnight or did it get worse over time? 
Thanks ❤
