Does any one use Ovulation Predictor strips for BC? I am thinking about getting some. Where can I find some really cheap?

How often should I use them? One a day?

If you want to save money, and find out a lot about your body, you may want to consider using Fertility Awareness Method, or FAM. You can find out a lot about it on the Internet and from the book Taking Charge of Your Fertility by Toni Weschler. I used this method for 4 years as BC and then was able to use it to time intercourse and got pregnant our second try.

The method involves charting your waking termperature and observing other fertility signs such as cervical placement, cervical mucous, and your own personal fertility signals. You chart these signs and observe the patterns they reveal. For example, you may notice an increase in cervical mucous with an eggwhite-like quality before you ovulate, then a dip in waking temperature followed by a significant rise. This would mean you ovulated.

I eventually got to the point where I didn't tracks temps but only cervical mucous, but I'm also very regular and we used condoms as back up if there was any doubt. The true way to use FAM for BC is to chart religiously and abstain starting at the first signs of fertility and for 3 days after you ovulate.

The other advantage to FAM is you can find out other things about your reproductive health. Because you're always aware of what's going on you can identify cervical changes that may be a signal of illness, and sometimes hormonal or thyroid imbalances. I have a friend trying to get pregnant and she's identified a progesterone deficiency based on the low temps she sees after she ovulates.

Obviously, I'm a big proponent! Sorry this gotten so long. I hope you find a method that works for you. And hats off to you for looking into alternatives to hormone BC!

Thanks for the info, I have been using NFP for a while, but w/ BFing, it's a bit more complicated For now we are doing something else if I have any CM (which seems to be quite a bit) and it's hard for me to take my temp on time everyday. I have TCOYF, but it's out on loan right now to a cousin.

Wouldn't it be difficult to use as BC, as sperm lives up to 3 days and the OP will only tell you up to 24 hour in advance? For example, if you have IC on Monday p.m. and then Wed. am the OP is positivethen you will probably still have live sperm hanging around when you ovulate. kwim

Yeah, you can't really rely on OPK's for birth control, because they don't predict ovulation soon enough to stop relations in time. I think this was even mentioned in TCOYF....but I could be wrong.

I'm having a hard time with my charting, too, as my signs seem to be pretty off-kilter due to nursing. But I DO make it a priority to take my temp every day - I set the alarm on my watch, take my temp when it goes off (I keep my digital thermometer with a memory function under my pillow), then go back to sleep.

I also bought the Ovusoft charting software, and I really like that a lot - it detected a thermal shift that I never would have caught! It's not meant to be used for BC either, but I figure it was worth my money just to have an easier way to keep track of my charts - it's a big think when you have a toddler that likes to run off with chart & pencil whenever he finds it!
