Pregnancy needs sperm to reach the egg, that only happens through intercourse. Touching or pressing breast has nothing to do with it. If you still have doubts about how conception works, a gynac can explain clearly.
Beta no, this will not cause pregnancy. There are a lot of myths floating around about these things. Pregnancy comes only from intercourse, nothing else.
No re, this does not cause pregnancy at all. Pregnancy only happens from intercourse around ovulation time, nothing to do with pressing breast. Dont confuse yourself with these things.
I had this same confusion when I was younger actually. Someone properly explained to me that it only happens from sex, not from any touching. So no need to worry about this.
