I had surgery on my beast 02/25/13 for the 3rd time less then a year. i sometimes take my necon birth control pills. what are some pregnancy signs.

Some small changes: A woman of childbearing age who has some nausea (with or without vomiting), some fatigue (feels less energetic), a sharper/stronger sense of smell, mild soreness/swelling of her breasts, and maybe some food aversions and cravings . . . Could be pregnant. Symptoms can occur before missing a period. She can do a urine pregnancy test 1 week after missing her period, or if she is worried about it.
