I have taken duphaston at day 17 after my last period i took two pills for 10 days and then after 6 days of stopping i have been feeling like sick and my body temperature rises and i still feel like i need a blanket i think i might be pregnant ?

Hard to tell...: 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 if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If fever occurs, a doctor can check for a typical illness or infection.
