what the best method to not get pregnancy?

best device for her is birth control pills

Ideally, you should start taking this pill on day one of your menstrual cycle

One tablet is taken every day for 21 days and you then have a seven day break

During your seven day break, the levels of the hormones in your blood drop, which results in a withdrawal bleed that is similar to your normal period.

90 % virgins do not bleed

If you are both committed to a loving, sexual relationship you should always use condoms. This will protect against both sexually transmitted diseases and pregnancy. Condoms (when used properly) are about 98% effective as birth control. If you want her to use something, she can go to a gynecologist and request birth control pills, but it is much easier to obtain condoms and safer in the long run.

Nothing is 100% effective other than abstinence. But, you should be using a condom every time and your girlfriend should probably go on birth control like the pill or which ever type she feels the most comfortable with.

Hope this helps!

Use condom... apart frm protection against pregnancy it also protects against sexually transmitted disease.

Give ipill to ur gf within 72 hrs of doing sex in case condom breaks or tears during sex.

birth control is the most effective with condoms they are great but they don't always work they can leak or break so try the pill for her just make sure she is not taking medication for anything while taking birth control otherwise the pill won't work
