You should start charting...that is the BEST way to determine IF you are ovulating. That way you will have a good idea of what your cycle is doing. I tried Ovulex two times for 3 months each time and it didn't do anything. I just recently stopped them this month because I gave up on it.
As far as your diet goes, you should cut back on caffiene and sugar while ttc. You can also take evening primrose oil to help with cervical mucus. You can also try B6 to help with your luteal phase. It helps you to have a normal length luteal phase. Also I think that you can use musinex to try to help with cervical mucus, but I would look into that one more.
