I'm not a big fan of supplements to be honest. We tried for 3 years in total and I tried so many things in that time. From memory - seven seas, pregnacare, own brand conception vitamins, omega 3, coq10, zinc. I'm sure I've forgotten plenty. By the time we were coming up to the 3 year mark, I'd had enough and stopped everything. Just took folic acid and vitamin D. Then much to our surprise, we finally caught after all that time. It was also the most relaxed we'd been in months as we really had given up.
