Pregnant pcos

Okay so I'm only 8 weeks roughly, and I have pcos. And I'm so scared that it could harm the baby, I go in Monday to my gyno, but I'm just praying in the meantime everything will be okay until then. Is it okay for me to have sight period cramp feelings sparatically, and also what can I do about the sickness, I have thrown up horribly like 5 times today. Is there anything I can do about that
