Temping works to confirm ovulation, but isn't good to use for trying to predict ovulation. You should use an Ovulation Predictor Kit (which is a lot like a home pregnancy test, just a strip you pee on) to help you know when to time intercourse. Sorry if you already know that, just trying to break it down as best I can.
Ovulation Calendar and Ovulation Chart - Fertility Charting has an AMAZING "course" on charting. It teaches you exactly how to chart properly, and their website keeps track of your info and analyzes it to figure out when you ovulated based on temps, body signs (like cervical mucus), OPKs, etc.
I haven't had a regular cycle yet since my son was born, but if my period shows up in nine days or so, my plan for next cycle is:
ClearBlue Easy Fertility Monitor
Two kinds of OPKs
Charting
FertilAid vitamin/herb blend
120mg Soy Isoflavones on cycle days 5-9
It's really not necessary to TRIPLE up on ovulation predictors, but I have it all available to me right now, so I'm just gonna go for it. Some people will use the cheap OPKs from online and then use a more expensive store brand to verify the positive cheap OPKs, because sometimes the cheapies can be a little hard to read. (Some people get blaring results though! It just depends on the person.)
I hope that helps you some! I'm sorry you landed here because it means you're having a difficult journey, but at the same time I'm glad you found us. It really is a great place to meet other kind, intelligent, and like-minded women.
