Should I just have the IUI

Hey... I'm writing to get your advice I have PCOS and have been TTC for 3 years now naturally. I underwent 1 unsuccessful cycle of clomid with no IUI and now just trying fertilaide which doesn't seem to be working for me.... I have two cousins which underwent an IUI procedure and have children to show for it.... I guess my hold up is the cost and just really wanted to achieve pregnancy as natural as possible but now I'm begining to lose hope and thinking of starting 2 cycle of clomid with the IUI procedure... what do you guys think? 😕
