Does plan B emergency contraception work if you only take 1 pill? I?
Nope! Your body needs the total amount of hormones from BOTH pills for it prevent ovulation and thin the lining uterus, plus thicken the mucous plug in your cervix.
In short it will not be effective
i presume you talkin about morning after pill. the pills itself wont work without taking the 2nd one 12 hours after the 1st.
No, you have to take the pills in the specified time frame. One is not enough.
There are two pills for a reason. They act together in preventing a woman from getting pregnant. Taking just one may prevent you from not getting pregnant.
