Hi ladies! Great thread
I am a vegan since April 2012 and started TTC just this month. So my suggestion will be plant-based foods only, but from what I am reading, deli meats and undercooked animal products are not ideal anyway.
I have discovered that buckwheat is packed in nutrients and has all 9 protein aminoacids that the body cannot synthesize. So I have invented a recipe including lentils, olive oil, buckwheat, parsley, tomatoes.
You can find this one here: https://thenonhiphippies.org/2013/07/30/beluga-lentils-and-buckwheat-iron-loaded-super-meal/
Also, when it comes to smoothies, here is another invention of mine, packed with nutrients: https://thenonhiphippies.org/2013/05/07/the-magical-kiwi-smoothie-and-why-fresh-fruit-juices-rule/
Lemon water, as already discussed, is a great detox and a nice alternative for coffee, when you want something warm to sip.
Broccoli is also full of calcium and so is bok choy and almonds.
When it comes to folic acid, you can get it by eating beans, lentils and dark leafy greens.
I have been taking the Solgar Prenatal since February 2013 and my blood tests came back excellent in July. I am not sure if it is the multivitamin, the diet or both, but it works.
Plus, I suggest that you google vegan diet and PCOS. I have no personal experience, but many women claim that they got rid of their PCOS via a plant based diet
