Hi Sushigirl,
IVF/IUI is really for those that in a way, give up hope in trying naturally.
Also, the cost is rather high as well. I will not really recommend it.
Like what MulMul89 suggested, probably try go for fertility check for both of yourself, and hubby. To see if there's any fertility issue first. If don't have, maybe can try go for multivitamins or supplements to build up both your body. Exercise, relaxing (staycation or even massage or something that keep you out of mind) play a part too.
Important is don't over stress yourself. Jiayou!
