i've been without my period for 4 months(sure not pregnant, abstinence) cuz loss of weight and exercise but i had intercorse and didnt use condom since the begining so i took one pill of next choice, DO i have to take the other one???

You did not take Next Choice correctly. I don't know what the consequences will be.

Do you have a primary care physician or a gynecologist? I think you need to address the cause of not having a period for 4 months.

Not knowing when you are ovulating and having unprotected sex makes it very complicated and uncertain to know if you have conceived or not conceived.

Be careful when taking an emergency contraception such as Next Choice. Such pills contain high doses of the same hormones found in certain birth control pills. You don't want to be messing up your hormone levels, especially since you are not having regular periods.

yeap so i took the pill cuz im actually dont know when is gonna be my nextr period, so i dunno wanna be like freaking out around, but well knowing the fact that im not ovulating so far,i tho one was enough

If I understand you, you have not had a period in 4 months because you have lost weight and exercise. Excessive exercise, such as an athlete in training, and extreme weight loss can cause an absence of periods.

Yes, you are supposed to take both pills for it to be effective.

Here are the directions from the website for Next Choice:

Next Choice® has only 2 tablets:

• The first one should be taken within
  72 hours (3 days) of having unprotected sex, sexual attack, or a known or suspected contraceptive failure, and a study shows a greater effect when taken sooner
• The second one should be taken 12 hours after the first tablet is taken
