Your best bet is to use an alternate form of birth control (e.g., condoms, diaphragm + spermicide, spermicide alone, sponge). It is difficult to predict when ovulation is after coming off the pill as it sometimes takes a little while for your body to go back to normal, so your cycle can be erratic.
If you're not interested in a pregnancy right now, don't take any risks.
