onto the next round

We are starting our 7th cycle of IUI. Insurance pays 💯 for IUI and I think we will just keep doing it. It's bound to work eventually right?!  With meds I'm able to ovulate 1-3 beautiful follicles each cycle and my husband has amazing sperm. I really think it's just a matter of time. Do you think I'm crazy? Everyone in our families keep pushing us to move towards IVF. But I'm just not sure I want to :( Any advice?
