bbs are sore, but not sure about that because of the BF. They are very sore on the sides and feeling fuller. However, I am also leaking all the time which I do not understand. Maybe one of you gals have had some experiences to share. I have also felt icky like stomach issues and do not want to eat, but feel better after. I do not want to test until I cannot take it any more. With the last 4, I have never been able to get a BFP before AF is supposed to arrive.
