Hi Alisia, I've used natural fertility management techniques (charting etc) for contraception and conception for almost 5 years now and in my experience usually when your temp goes back down it means you are not pregnant. What you want to see is your temp rising and staying high after you ovulate. You will often get a tiny dip in temp the day before you O then it goes up and stays up if you are pregnant. One importnant thing to note is once you have seen the temp rise it means the egg has already been released and if you then start BD-ing it's often too late. If you don't get your BFP this month make sure you start trying several days early and continue until several days after your tmp rise. A herbal supplement that is good to try is Chaste Tree (sometimes called Vitex). Take this whilst you are TTC and then stop once your get that fabulous BFP. There is also a very good book called Natural Fertility Management by Francesca Naish avalable which discusses the NFM techniques in detail. I have never fallen pregnant "by accident" and we conceived our DS within 3 months of trying and our current princess in waiting on the first cycle and also my Husband and I use no artificial contraception at all and haven't since 2003. It's a great technique once you become confident and get to know your body, you'll never go back!

Good luck, I hope you are in the "family way" really soon.
