<s>[INST] Hi thereI jave had pcos for the last couple of years but have been actively trying to concieve but with no luck.I started taking metformin 500gm in november to help with my polycystic ovarys and since then i have not had my period. It is now the 5th of january 2018, could i be pregnant or is it just my pcos causing my flow to be late?Please keep in mind that i am overweight and the only tjings affecting me is that im more tired than usual, have lower back aches, and have cramps but not everyday.. [/INST] Hi There, After going through your question, I am of the opinion that:1) Yes, infertility caused by PCs can be treated. There are many patients suffering from PCs who conceive naturally.2) Metformin helps to overcome insulin resistance and thus combats hormonal problems associated with PCs.3) Amenorrhea which follows unprotected sexual intercourse can lead to pregnancy.4) My suggestion is that you get a urine pregnancy test done at home. If that is positive, it means you are pregnant.5) The symptoms also point vaguely towards pregnancy, and testing is the only way to tell. I hope this helped.  </s>
