Well... I was looking for ideas and found a site that said you needed 3 things... (1) good eggs, (2) good sperm and therefore (3) a good embyro...
I was like... yeah great LOL!

I tried pineapple- buy 1 on the day of transfer- divide into 5... eat core and all a piece each day. On those cycles with pineapple I got a BFP but chem pregnancy. Without pineapple... nothing.

Best of luck
