pcos irregular periods and pregnancy.

Hello ladies I have few questions if anyone can help? I recently got married and I have pcos and curious how to track my ovulation.. as my period are irregular. How and when is best to take a test. I have read few posts mentioning anyone with pcos not able to detect pregnancy till later down the line. Also if you have pcos do you bleed through out your pregnancy and blood clots? I have been reading few posts and would like some clarification from anyone with further info would be helpful.
