I had protected sex one week ago and after that i been having this stomach bloat on and off and i have tender breast that feel swollen.am im pregnant?

Take pregnancy test: Let's be clear: you're not going to "feel" pregnant from protected sex 2 days ago. However, you might be pregnant from unprotected sex a while a go. Furthermore, it's not clear what you mean by "protected". Birth control pills/shots, diaphragms etc lower risk for pregnancy but do nothing to prevent sexually transmitted diseases/infections. That's why he has to wear a condom each & every time.
