Natural emergency contraceptive?

I know there is the iud and all the things but are there more ways to prevent pregnancy? Yoga? Strecthes? Anything? The reason i ask is because the condom broke without us realising and he finished inside me. I took plan b and showered right after and my period is supposed to start tommorrow - please help! Ive heard ginger root tea is an herb used to prevent pregnancy and stimulate your menstral cycle. I already drank a cup of that and will continue to probably drink it #birthcontrol #condom #emergencycontraceptive
