I thank you for your compliment, and i am proud of my English because it is self taught, i am a rather good autodidact, which is also the reason why i have the knowledge of breast cancer, i dug in when my mother was diagnosed with it.
Congratulations on the pregnancy, if there is no suspicion yet, so no knots you felt yourself with your hands, you should suckle rather long, and wait at least 3 month after you stopped that for a mammography screening, because the tissue gets compressed and the early diagnosis is harder to make.
You should however, start to examine your own breast with regularity, that is something isolated from the mammography that can be recommended to about any women, do it once a month to detect new knots early and have the clarified as soon as possible.
In general the breast is the most soft about a week after the beginning of the period that would be a good time to examine.
