4 years ttc #1 ๐Ÿ˜”

Kelly
Hey there. My husband and I have been trying for 4 years for #1. We have completed 6 IUI's all negative and 2 IVF cycles that resulted in negatives. The 1st one ended up being a chemical. We took the summer off because it was getting to be too much. 
Has anyone tried any natural things that helped with a positive. I think I'd like to try the natural route for a few months before getting back into IVF. 
I've heard of Fertilaid. Anyone know much about it?
Thanks!
