You can order preseed from Amazon.com Or, you can use astroglide. It worked really well for me.
Start an account on Fertility Friend (
www.fertilityfriend.com ) for charting. They will give you a VIP membership for free for 30 days. FF won't verify ovulation until three days after the fact, but at least you'll know that you did indeed ovulate or not. You'll want to take your temp every morning when you wake up, preferrably at or around the same time each day. I know of no "easy" way to check your cm and cp except by sticking your very clean fingers up there and seeing what you find. When your cp is nice and high, you are probably very fertile. As well, if you see ewcm, start having sex! And keep having a lot of sex until FF says you have ovulated.
Start taking Evening Primrose Oil to help your body create ewcm. I don't know if it really helps, but I started taking chlorophyll tablets because I was having light periods and wanted to increase my blood supply. It might have worked because the period before I became pregnant was good and heavy. Or at least heavier than my periods had been before.
Also, be sure to take your prenatals and extra folic acid.
Good luck!
