I took plan B about 5 days ago but I weigh 220 pounds, so I'm well over the weight limit. Has anyone else been this heavy and had it still work? Today I am feeling dizzy and have an upset stomach, I hope it's the plan b and not pregnancy. Just wondering how accurate the weight limit is
Plan B work if overweight?

I am 220lbs and Plan b worked fine for me. I had no side effects but being super emotional the next day. First period was on time second period was a week late. If you feel like stressing out then hey do it there is nothing you can do but be stressed out. I know I cried a lot and googled my behind off and couldn't find a clear answer. So here : yes it does work when you are overweight. And now let us all be more responsible instead of following our p...

Can you be sure that you would have conceived had you not used Plan B?

Did the plan B work for you? Me and my friend recently had sex and the condom broke, we went and got a plan B. But she's over 175lbs

Ask for the pill Ulipristal Acetate instead. It covers larger women. It can even work if she was ovulating, which Plan B does not.

I tried to respond to your question a couple of minutes ago, but I can't see that it has been added to your question. This may be because I included a link.
Just in case, here is what the page says, without the link in my response:
'Are emergency contraceptive pills effective for overweight or obese women?
Maybe. All emergency contraceptive pills, regardless of type, appear to be significantly less effective for obese women. This is an important consideration in the United States, where over 35% of adults are obese.
In clinical trials of women using EC pills (progestin-only, such as Plan B One-Step or Next Choice, or ulipristal acetate, such as ella) obese women (with a body mass index, or BMI, of 30 or greater) became pregnant over 3 times more often than non-obese women. However, ulipristal acetate (ella) may be more effective for overweight or obese women than progestin-only EC (Plan B One-Step, Next Choice). EC appears to decline in efficacy as BMI increases; in fact, for women with a BMI of 26 or over who used progestin-only EC, pregnancy rates were no different than would be expected if they hadn't used EC at all. Ulipristal acetate (ella) appeared to lose effectiveness at a higher BMI threshold of 35.1, 2 Increasing the dose of EC for overweight or obese women has not been studied and is not currently recommended.
The most effective choice for emergency contraception for overweight or obese women is the copper IUD. The effectiveness of the copper IUD used as EC is greater than 99%, no matter how much you weigh (and it provides at least 10 years of excellent ongoing contraception).
Click here to calculate your BMI. If your BMI is 26 or greater, consider calling your health care provider to get a copper IUD or ella. If you can't get an IUD or ella within 5 days of unprotected sex, but you can get progestin-only EC (like Plan B One-Step or Next Choice), take it as soon as possible.'

I had read that as well from that website. But I have been having symptoms that could be from the plan b. Like headaches and dizziness and sore stomach, so I was thinking it had worked. Didn't know if anyone else had similar side effects

I agree that they sound like symptoms of the Plan B. I had those symptoms from it.
Also, although it says that Plan B can be less effective in overweight women, it's also worth balancing that with the fact that being overweight can also affect the chances of becoming pregnant.
It sounds to me as though you're just going through the effects of the Plan B.

Hi...
I recently took next choice one step pill, I know this is somewhat old but I was wondering if it did work. I'm at least 234-240, took it probably 36-40 after the incident and it's been almost 2 weeks since and my period isn't due for another 2 days. I've been feeling dizzy and nauseous, my boobs hurt. I had a little cramping like 3 days after taking the pill but that's about it. I'm wondering if it's even going to work because of my weight plus I believe I was already ovulating that weekend of the incident. I've read of other reviews about females getting pregnant after taking these EC's I'm just wondering if this pill is really working for me. I have not tested yet but plan on it in about 3 days . I guess we'll see what happens.
