Usually but not necessarily. Some women can have one or two periods after they become pregnant but it is somewhat rare. The best way to see if you are pregnant is to get a test.

No. Two normal heavy periods and no symptoms of pregnancy sound like your definitely not pregnant.
While it is rare, some women do continue to have periods (I know a couple). Most likely is is heavy spotting due to being pregnant. That is much more common.

Around two weeks after intercourse.
