Fertility/ovulation

Kayla
My husband and I are only using the withdrawal method, but I've been considering using the ovulation tracking metho also. We don't really want kids right now due to finances, but we won't be upset about a baby either. I've just been thinking that maybe having another method would possibly be a good idea. I can't really afford BC and I can't really take anything due to my medications... So the pull out metho has been working wondrous for us. How would I go about starting the ovulation method?
