<s>[INST] I have unregularly period because I have PCOS I had took birth control for 12 months but when I had stopped taking them my period was regular for just three months my 4th one is late now.. I  was wondering if I should take something else now ? and if the total fertility supplement PCOS will help in my case ? I will appreciate your kind answer Im  really tired because of this ...thank you [/INST] Hi. Treatment for PCs begins with weight loss and metformin, if either or both are indicated, and then is individualized depending on the patients reproductive needs: oral contraception supplemented with Kantian Chat Doctor. To reinforce weight reduction+/- metformin is the recommended therapy. Role of fertility supplements is questionable. Consult your obstetrician for further management. Hope this helps. Take care. </s>
