Can you have pregnancy symptoms in 1 week in 5 days after conception?

Occasionally: That is almost too soon, but if a woman has incredibly good body awareness, she can notice changes in her body at about 12 days after conception. The easiest way to tell is to wait a few days to see if her period comes. If she gets her normal, regular period, she is not pregnant. If she misses her period by a few days, and is usually regular, she can check a home pregnancy test.
