Zinc and folate at the time of conception is vital.
take Zinc alone at night ad make sure you have 1000mg of Vit c everyday in the 2ww, it is needed for healthy implantation and lots of B-Vitamins, liquid is best, having a berocca daily will do the trick as this will ensure you absorb all the vitamin/s.

My DD was concieved via AIH/IUI and I did all the above and my Dr put me on the above Dr including Berocca. I'm on the above diet again and trying naturally, this is our last cycle before we do IUI again.

goodluck lisa.
