if it has any validation so I googled & this what I found.
On another forum on another site a lady said-
My dr said there is some merit to the pineapple thing. But the advice she gave me was 1-1.5 servings of pineapple a day and the majority needs to be core. Only have until 14 DPO/BFP because after that it could affect miscarriage
Thats interesting. I have a book that says to avoid pineapple when you are trying to get pregnant. I know you have to eat like 7 whole fresh pineapples to have any effects but it says to avoid them.
I ate it on 4 rounds of IVFs and got pg 3 times. Not sure if it helps but ate it anyway. Make sure only eat it 5 days in total. 2 days before transfer and 3 days after transfer. It will cause the MC if we eat it entire of 2ww.
Oh, make sure to keep your feet warm as well.
