Not a concern: The progesterone hormone in Plan B is safe to take while breastfeeding and will not harm your child. Exclusive breastfeeding will provide you with some protection but you might want to discuss with your doctor about going on the "mini pill" for better reliability. This is a better option that episodically using Plan B.

Depends on ur weight: Plan B is usually effective up to 5 days after unprotected sex, but most effective within first 72hrs (~88% reduction in unintended pregnancy). However recent studies found that Plan B is less effective in women weighing >165lbs, and ineffective if >175lbs. It does not stay in system more than a few days.

How long will plan B be on my system? What effects long term does it have? What do I do now that I drank it?

Plan B elimination: The progesterone in Plan B is 99% gone within 7 days. It may take up to 2 months for your period cycles to get back to normal. This may include bleeding at the wrong time or skipped periods. You'll want to take a home urine pregnancy test using the first urine of the morning 14 days after you took the Plan B. If that test is negative, you're not pregnant.

What happens to the system is Plan B is taken more than twice a month on top of borth control?

What happens to the system is Plan B is taken more than twice a month on top of borth control?

Irregular bleeding: If you are taking a regular birth control pill daily, you should not need plan b. But if you have taken it twice and have not missed any pills, you may not see any change in your cycle, or you may see irregular bleeding. You should consider using condoms and spermicide in addition to your birth control pills.

Hello I am very worried, I had 3 accidents this week and I took plan B 3 times this week, can it hurt my system and should I be worried?

Hello I am very worried, I had 3 accidents this week and I took plan B 3 times this week, can it hurt my system and should I be worried?

Yes, be worried!: Don't be worried about danger of taking Plan B three times but you should be very worried about three "accidents" in one week. Three accidents is no accident but the result of very poor planning. You need to get a form of contraception that you can trust. For a teen who is fairly sexually active, an IUD or Nexplanon would be my advice. (Along with condoms for STD protection)

If I took Plan B on Sun for a mishap on sat. And had it happen again this wed do I need to take another plan B? Is it still in my system?

Another planB: You would need another.....This is not great for your system. I would highly recommend looking into other forms of birth control like the pill, Nexplanon, Depo Provera, (medroxyprogesterone) condoms......so that you don't need to keep taking Plan B so often.

Hello I took plan b one step yesterday and the next day, the comdom came off inside me. Is the medicine will in my system?

Hello I took plan b one step yesterday and the next day, the comdom came off inside me. Is the medicine will in my system?

Maybe will work: First, one must stop having these little accidents. Secondly, there are no research studies that test this situation of putting sperm into a fertile woman one or two days after Plan B. Thirdly, life can be full of surprises... so always do a home urine pregnancy test 3 weeks after sex, because emergency contraception works most of the time, but not all of the time.
