Does plan b work after 1 day?

Are you one of those people who like to live on the edge? Do you love taking risks and living recklessly? Well, good for you! But when it comes to contraception, playing with fire is not advised. There are times when even the most careful among us may find themselves in a situation where they need emergency contraception. In this article, we will address whether Plan B works after 1 day.

What is Plan B?

Before discussing its effectiveness after one day, let us first understand what Plan B is. It’s an emergency contraceptive that prevents pregnancy by delaying ovulation or preventing fertilization if ovulation has already occurred. It contains a synthetic form of the hormone progesterone called levonorgestrel.

How Does Levonorgestrel work?

Levonorgestrel inhibits ovulation so that there won’t be any egg released from the ovaries which can interact with sperm cells leading up to fertilization. Additionally, it also changes cervical mucus thickness and makes it difficult for sperm to reach eggs since they cannot swim well in thick mucus.

So now that we know how Plan B works let’s answer the question at hand: does Plan B work after 1 day?

The Best Time To Take PlanB

The sooner you take it, the better as far as efficiency goes – hence why some folks call it ‘the morning-after pill’! According to research studies carried out on levonorgestrel-based emergency contraceptives like Plan b One-Step, delay lowers their efficacy rates over time, with studies indicating anywhere between 52% down to lowering risk rates of 0% at four days following unprotected sex.

However, seven studies summarized through Europearly findings suggests levonorgestral body concentrations remain above levels expected necessary for effective suppression of LH/FSH secretion 5 days following take of the drug.

Although Plan B is most effective in preventing pregnancy when taken within 72 hours (3days) after sex, it can still work up to five days later. Therefore, say you were hesitant or had other things going on and just could not make it to your local pharmacy – well ‼️ don’t fret! 💆🏽‍♀️ The chances are high that you would wake up the next day worry-free!

How To Take PlanB

Let’s talk about how to use Plan B effectively. It usually comes as a single tablet containing 1.5mg levonorgestrel which is ingested orally without water before meals et voila! You’re good to go 😀.

However, there are several factors associated with effectiveness: e.g., if vomiting occurs within a few hours after ingestion (an often-lamented effect tied with birth control side effects generally), seek advice from professionals or consider taking another pill.

Side Effects Of PlanB?

Now let us touch upon possible side effects which include dizziness, headache, lower abdominal pain like menstrual cramps and spotting of blood followed by altered period cycle onset. Although these symptoms may sound scary for some people, they should not last long (they typically go away on their own within a few days). If persistent serious concerns arise over any symptoms experienced Contact specialist medic and/or refer to included medication guides – lest pharmaceutically biased outcomes distort consumer understanding!

So now you know…don’t let contraceptive emergencies stress out your zen-like existence 🧘🏾‍♂️💆🏻‍♀️😌 But also be responsible 🙂 There’s always time for fun and living recklessly tomorrow 😜!
