Regarding Fertility Treatment - IUI.

I am trying for a baby for more than a year now and yet no luck. I am 30.5 years old and my husband is 32.5 years old. I am visiting a gyno and have done HCG and follicular study so far. everything seems to be normal. and my husnand also did semen analysis and looks lile the count is average but okay. we both took medicines for nearly 8 months. i am fed up of medicines and injections every month. When my friend got conceived via IUI treatment, I wanted to know from my gyno if I can try that and she said okay. I recently met up with a general doctor and she gave me a contact number telling she is one of the best gyno in my area and to go for a second opinion.  I am confused if we should try naturally for a few more months, do IUI this month or consult that gyno for second opinion. Please help, thanks.
