i think that's about all you need to do. as long as you cover your fertile window you should be fine unless you think you have problems with producing enough CM? i myself use preseed - have been for months, but only because we have always used something and i didn't want to use the kind that kills the little men. i do temp, opk, prenatals, and preseed, but that's all. i used to use mucinex and all sorts of supplements,but it never worked so i gave up. the months i didn't go overboard using all that stuff are when i got my bfp's. even though they were losses, i still got pregnant.
