Cant get pregnant...

I have been trying to conceive now for a little over 3 years i know im only 22 (23 this year) but nothing I have never caught pregnant and it's scaring me know. I have PCOS doctor told me to lose weight bmi of 33 so obese. He wanted me to be at least 29 or under. I am now 28.8 bmi and continuing to lose weight but nothing :(

I take metformin everyday two a day.

And clomid (one tablet) days 2-6. Anyone else in the same boat?
