I bled after 10 days of duphaston, i'm diagnosed with pcos. hpts were nega but i sometimes feel little gas bubbles which acc. to my search is how the babies movements feel. it's been 18w since my last sex. should i still be worried about pregnancy?

Tests are accurate: 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. Can test by 3 weeks after sex (by 3 weeks after when conception might have occurred), or 1 week after missing a regular period or missing a withdrawal period.
