I have only had success with FET's.

Our 3rd FET resulted in DD - now 21 months and our 5th resulted in the twins - now 9 weeks old.

All our kids are from the same batch of embryo's so the boys were effectively on ice for 2 years. Oh and also they were all day 3 FET's as well.

Good luck, I hope your little frosty is your sticky bubba.
