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

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

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

I took emergency contraceptive two weeks in a row now I've been bleeding for almost 2 weeks. Can I take birth control pills to stop the bleeding?

You can but...: You can utilize the oral contraceptive, but Plan B was a hormonal product as well which is why you are having withdrawal bleeding. Consider "riding this bleeding out" and allow the body to reset on its' own. By the way, use a alternative non hormonal contraceptive until this period passes next month. ...Read more

Should I take emergency contraceptive if I've been on birth control pills for 10 days and had unprotected sex? I thought after 7 days was effective.

I had unprotected sex but took all my birth control pills correctly, I had sex again and used emergency contraceptive but my breasts hurt, what does?

High hormone levels: Emergency bc and regular birth control have hormones. Too high levels of hormones cause side effects. Sounds to me as if you don't trust your pills. If u take every day, if you miss. Consider long acting options of iud and implant. They're the most effective and easy! ...Read more

I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

Maybe: If you were taking the birth control pills regularly it is very unlikely that you would become pregnant...Even with a broken condom. The condom is helping very little with your contraception but using a condom can be a good way to prevent some stds, not all. Plan b could alter your period. Just begin your next pill cycle on the correct day. Get a pregnancy test done to prove you are not pregnant. ...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

Can plan b cause you to ovulate even if you're on birth control pills because of the decrese in hormones after 120hrs?

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

I missed 2 birth control pills from Friday and Saturday but took them Sunday. If I had unprotected sex with my boyfriend Sunday should I take plan b?

Wouldn't hurt: One of the actions of the pill is preventing egg release. No egg in the system=no pregnancy if exposed. If you miss pills, the hormone level they provide drops and an egg could be released. If you have trouble remembering you need to consider other forms of BC like an implant or IUD. ...Read more
