Congrats on the witch making her appearance!

I have always used FF (Fertility Friend) but I tried to use another online site called
www.fertilitycircle.com. Personally, I didn't like it. I found FF more user friendly. You can change the settings to celsius, what I would recommend you to do is play with the setting for a bit. Its really easy to use (FF). When you log in and you are looking at the chart screen, you will see on the left hand side where it says menu, as you scroll through each item, it give you a list of different categories that you can go into to make your changes. As far as knowing that you are O'ing, there is really only one way that you can know for sure and that is to chart. My advice to you is chart but also use opks to help better pinpoint your O day. Always check to see what type of cm you have and always make a note of it (the most fertile you see for the day). Try not to disgard temps and try to temp consistently at the same time. I had two spare thermo's also just in case one broke.

I think what worked for me this cycle was prenatal vitamins/supplements, DH was taking multivitamins, hardly no alcohol, virtually no caffeine, drinking lots of green tea before O, using opks, and drinking plenty of water. Oh, of course charting/temping.

Gosh, sorry so long, I wrote a book! Good luck to you! May you be blessed with a bfp very soon! (((((((Baby Vibes)))))))
