Can i be preganant? i have nausea, and my breast are tender, i feel tired most of the time and i have abdominal cramps. please advice

Hard to guess: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing her regular period. Her primary care or Ob-Gyn doctor can evaluate, if there are persistent or worrisome symptoms.
