Most of the stuff that is marketed as "aiding implantation" does nothing at all, and when people take too high a dose or take many things all together it can actually be harmful. Please run everything past me before doing it as some of the supplements are actively harmful. Eating a lot of good food and following the doc's guidelines for how long to rest after transfer are most important. Your body knows how to implant a pregnancy. If you really want to do something you can eat fresh pineapple including the core and the brazil nuts, which are harmless.
I am so happy you gained a little weight back!
