No: If you are on birth control then there is no reason to be taking Plan B. Plan B is for those who are not on birth control to take after having sex. Using Plan B would not make the birth control pills less effective it is just not necessary to take Plan B when you were already protected in the first place ...Read more

Birth Control Pills (Definition)

Also known as oral contraceptives, birth control pills are highly effective oral medications that use hormones to prevent pregnancy. There are two main types of birth control pills: one with estrogen and progestin (also known as the combination pill) and one with just progestin. The two main ways they prevent pregnancy are: 1) The hormones thicken the cervical mucous, which keeps sperm from entering the uterus on their way to the egg; and 2) By maintaining a level of hormone in the blood stream that prevents the ...Read more

Can you ovulate after taking plan b if you are on birth control pills and take them religiously?

Very unlikely: It is very unlikely that you would get pregnant which is obviously what you are asking taking both Plan B and birth control pills correctly but, if you are taking your pills correctly, there is no reason to take Plan B. It would be better to use condoms and decrease the risk of STDs in addition to increasing the contraceptive effectiveness. Hope this helps. ...Read more

I took plan b and a two days later I had cramps and spotting. I am on birth control pills but was worried they failed. Is it implantation or plan b?

Can taking the Plan B pill while on birth control pills delay your period during the placebo week?

Can taking the Plan B pill while on birth control pills delay your period during the placebo week?

I believe so.: I am not a gynecologist, but my understanding is that Plan B is a high dose of hormones that induce shedding of the lining of the uterus (preventing an egg/embryo from implanting). Taking Plan B while taking placebo (which are sugar pills) will be like taking Plan B by itself. Bleeding based on a new schedule caused by Plan B may be earlier or l8r than usual depending on how ur body reacts. ...Read more

Had unprotected sex while on birth control (pills), during off week, just started period, he ejaculated inside me, should I take plan b? Been on bc 1yr

Had unprotected sex while on birth control (pills), during off week, just started period, he ejaculated inside me, should I take plan b? Been on bc 1yr

Essentially no risk: If you were taking your bcp as prescribed and this was your off week, during which you had your period, you will have very, very low risk of getting pregnant. Resume taking your bcp as prescribed for the start of your 28 day cycle. Meanwhile you may want to refresh your education a bit about other hazards of unprotected sex, such as sexually transmitted diseases. ...Read more

What is the difference between the Plan B emergency contraceptive and regular birth control pills?

Mechanisms differ: Plan b is levonorgestrel. It alters the tubes to prevent passage of the eggs and sperm and prevent fertilization. It also alters the endometrium to prevent implantation. Birth control pills usually contain an estrogen and a progesterone. They suppress LH and FSH to prevent ovulation. They also alter the cervical mucous to prevent sperm from entering. ...Read more

I was off birth control pills for a month. In the first week of starting my pills again I had sex will my bc be effective or should I take plan b?

Uncertain: I don't know which oral contraceptive you are taking. You can check on-line to see how long it takes your particular birth control to be effective. Or your pharmacist can advise you. Depending on this info, you can make the decision as to whether or not, it would be productive to take Plan B One Step. ...Read more

I don't normally take birth control. But I had unprotected sex and was told if I take 3 birth control pills it works like plan b? Is this true? How?

I don't normally take birth control. But I had unprotected sex and was told if I take 3 birth control pills it works like plan b? Is this true? How?

Not exactly: Some pills are designed to be emergency contraception pills (those work best). Regular birth control pills have various hormones in them, and SOME types of those pills can be taken to try to prevent a pregnancy. One can also get an IUD, which works well as emergency contraception (ask one's Ob-Gyn doctor). A reference table can be found at: http://ec. Princeton. Edu/questions/dose. Html#dose ...Read more
