Hi, I have be diagnosed as having PCOS . My menstural cycles have been irregular, and my doc put me on clomid at first, and since my period did not come, and the pregnance test was negative, the doc put me on Susten 200mg for 7 days twice a day. But from the time i have started it, i m having nausea and feeling very tired and also hungry. Are these normal side effects? and i am worried that my period did not come and i tested negative on the pregnancy test
