I hope you're pregnant!! That would be wonderful! If by chance you are not, have you ever read Taking Charge of Your Fertility? It is EXCELLENT at helping you learn how your body works, even with irregular cycles. It'll help you learn when you're ovulating (after the fact), help you learn signs of when you might possibly be fertile, etc. I would highly recommend reading it if you haven't. If you do have something wrong, it also can help you figure out what it might be - such as if you luteal phase is too long or short, etc. It's very interesting and has helped many couple who thought they couldn't have babies to finally become pregnant after years of trying.
As for clomid, my sister has used that. It has helped her conceive her child. She has PCOS and she doesn't really ever ovulate but about once a year. Clomid was a blessing for them. But I would suggest reading the above book if you haven't already before trying Clomid because Clomid does have side effect, though I don't remember what they are.
Pretty much any time you have any cervical fluid (discharge) it means you might be fertile. If you read the book, it explains that the discharge is actually necessary for getting pregnant, as it helps transport the sperm to the needed area;-) If that sounds weird, read the book, it has even more weird things, but it makes so much sense and really opens the mind up to understanding the timing of getting pregnant.
Good luck and hopefully you'll be prego!!
