Oh lawd. No, Plan B should not ever be something you plan to rely on, only a backup when your chosen method fails (broken condom, miss multiple pills, the works). It’s in the name: Plan B, not plan A. It’s a massive dose of hormones, less effective than real birth control, and can’t even work if the timing is wrong. If you want to have sex without a condom and not get pregnant, use a routine hormonal birth control, not Plan B. The calendar method OP mentioned is another can of worms.
Okay okay I know technically it’s marketed and only approved to be used after sex, but if you know HOW levonorgestrel works, and you know your own cycle, you should be able to use it to your advantage to maximize the efficacy right??? Not as a long term birth control of course but using it once should be okay.
Levonorgestrel does the same thing whether you have sex or not because its function is to stop the LH surge in order to delay ovulation. Which then can prevent pregnancy ONLY IF you take it within the correct window of time, as in 1) not too early before ovulation that it’s out of your system before it has a chance to affect your LH, and 2) not too close to ovulation when it’s too late to stop the LH surge or after ovulation
But the only advice people have given is “that’s not technically what the label says”. So if I were to use it how it’s intended, I’d have to have unprotected sex this week in order to delay my ovulation for when it actually matters NEXT week. But like the plan b doesn’t know whether you have sex or not all it does is delay ovulation (provided you take it at the right time)
I don’t think they would promote it because it’s probably not good for long term use. Like it could mess up your next few cycles, which means you can’t reliably predict your fertile window. And people would probably take it multiple times in one cycle, which is definitely not good for you. My guess is that if they did market it as a before-sex ovulation delayer, then it would be by prescription only to prevent people from using it too often.
That’s true, I’m not like dead set on using it. If I end up not doing it then I’m just not going to have sex this weekend (sad because it’s my anniversary but I don’t want to get pregnant). I’m just looking for external validation that my reasoning is solid and I’m not just setting myself up for failure 😭
But I’m just thinking that if something goes wrong this weekend (ie condom rips), then plan b will be ineffective because ovulation will already be triggered. The only way plan b would be able to work effectively is if I take it today/tomorrow BEFORE the LH surge. And I don’t want to have sex without a condom, I just wanted a temporary buffer of time to get me out of my fertile window.
So far I haven’t seen a clear reasoning for why it could be bad. If I wait until later to take it then it will be ineffective, so it seems clear to me that taking it sooner does have a higher likelihood of delaying ovulation and thus making sure there’s no egg to fertilize. The only thing people are saying is that it’s “not the correct way to use it” which yes I know this would be off label, but what are the negative health consequences?
Whether you have sex or not the plan b will still have the same effect of delaying ovulation (depending on the timing ofc) and the same side effects. I’m not trying to be difficult I promise but i genuinely dont understand what the harm could be in taking it without having sex because no one here has explained it besides the fact that it’s off label. Like does plan b always have negative health consequences (besides the obvious benefit of not getting pregnant lol)?
plan b has not been study for safety or effectiveness when taken before sex, meaning that it could very well just not work at all. it’s also dosing yourself with a very large amount of hormones for no reason. i don’t understand why you won’t just hold off taking it until after sex (how it is intended to be taken anyways). also, say it would delay ovulation and you take it now, you could very well miss the timing of the pills lasting effect relative to you having sex, whereas if you wait-
-you know for a fact that you are delaying ovulation in time to allow the sperm to die before they have a chance to fertilize the egg. and before you say you don’t know when ovulation would be, you wouldn’t know when it’ll be whether you take it before or after sex anyways, what you do know is that taking plan b after sex has been researched for safety and effectiveness and therefore is the better option
also you only have one day throughout your entire period that you are able to conceive. there is no way to calculate when that day is save for an ovulation test and even then it’s iffy. if you ovulate before you have sex, you cannot get pregnant ANYWAYS. if you ovulate after and you take plan B, that plan b can push your ovulation date a bit later to give the sperm the 5 days that are needed for them all to have died. your reasoning is based on “but i think” rather than “it has been studied”
Yeah that mostly makes sense, other than the fact that I would be having sex 3-4 days before my predicted ovulation day, so around the time of my predicted LH surge. It’s possible that ovulation could happen earlier than predicted, which is why I was thinking would be more effective to take plan b a day or 2 before the predicted LH surge, that way the levonorgestrel would still be active within its half life before the predicted LH surge occurs. Taking plan b after the LH surge will do nothing.
Either way, I did more research into opill and that seems like a much better option. Especially because I’ve never taken any type of hormonal BC or plan b, so I don’t know how my body will tolerate it. And opill is almost guaranteed to start working within the time frame that I need it to either a MUCH lower dose of hormones.
I would love to see some research on using levonorgestrel or any other type of medication to intentionally delay ovulation. Like I’m sure there might be an applicability to people trying to conceive as well. I feel like it would have to be by prescription only though in order to prevent people from doing what I’m trying to do lol. Because again it is such a large dose of hormones meant to be used as a last resort and not preemptively.
Just in general I wish there were more short term contraceptive options that are available over the counter 😭 like condoms work yes, and there’s spermicide but that can be very irritating to some people. And for young people who are still on their parents health insurance or anyone who just wants some extra privacy, it’s hard navigating the options that are prescription only or involve any type of invasive procedure
