Morning after pill caused tender breasts but no period?

Thank you so much. I was honestly getting paranoid and was thinking about trying a test until I realize it was way too early to tell. The symptoms I've been having are really annoying tho (like the nausea) but I get that it might just be caused by the pill or the paranoia.

Yes, I have a horrible time if I have to take emergency contraception. Plan B (Levonorgestrel) doesn't agree with me at all. It especially causes me terrible depression.
I use Ella (Ulipristal Acetate), if I ever have an emergency, these days. Much less problems, for me, with that.

Your period will probably only be a week or two late, but some women do find it's longer.

You won't know when you're ovulating, if you rely on an app to estimate that, until your periods are regular, again.

I would have tried Ella but it's not really available here in my country. ECP's aren't really sold openly here and can only be bought if you're lucky enough to find a legit seller. With that being said, thank you for the help. It's only been a day since I missed a period but the anxiety is killing me. The symptoms mimic pregnancy which is freaking the hell out of me. I'll update whatever happens.

I should have said, My Way is also just Levonorgestrel. Same thing as Plan B.

Yes the symptoms are like pregnancy.

Ah I know I'm lucky in the UK as I can get Ella easily.

You're very welcome. Try not to worry, you were well passed your fertile days.

Now the nausea is killing me. Stomach discomforts and the feeling I'd vomit every chance I get ever since I took the pill. I was wondering how long will I be nauseous for? I know this is too early to be a pregnancy symptom and I'm kinda glad I'm having these symptoms this early (that means the pill must be working right?)

The pill isn't working, as there's nothing for it to do.
If you were approaching ovulation/fertile, then there would be something for it to do, if it had time.
As you're so far past ovulation, it's just giving you a huge dose of artificial hormone.

Unfortunately, that huge dose of artificial hormone often comes with side effects, as your body deals with it.
Everyone is different as to how long those last, what they are, & how severe they are.

Most women seem to report the worst of the symptoms being over in a week or two, but sometimes you get symptoms that go on longer, such as mood swings, &/or lack of periods, or irregular bleeding, for example. Some women report those taking months to subside. The worst seems to be over in a couple of weeks, though, for the majority of people we hear from.
I remember feeling much better after 2 weeks. I'd get almost suicidal during those 2 weeks.

Thank you so much for the help, you really helped calm my nerves (even just a little). It's been a few days after the pill (9 days) and now I'm feeling all the pregnancy symptoms possible except spotting (didn't spot, not even once).

I forgot to mention that immediately after the accident, maybe 2 hours at most, I took an ovulation test? I was pretty sure I wasn't ovulating (I was dry down there that day and I track my discharge too) but I panicked and thought why not try it. It turned out to be negative but since I took it in the middle of the day, I don't know if it had an accurate reading.

I understand you're worried, but, with regular, monthly periods, you could not be ovulating so late in your cycle. You were way past ovulation.

There's only approx 1 week per cycle/month that you are fertile. You weren't anywhere near it. You didn't need emergency contraception, as your menstrual cycle is regular, so you know where you are each month. If you'd used emergency contraception recently, so your cycle was knocked out, then I'd have been concerned that you wouldn't know when you were ovulating, but as that wasn't the case, & your periods are regular, you're fine.

You have pregnancy symptoms because of the huge dose of artificial hormone in the emergency pill you took. It's the same type of hormone (only artificial) that would be more present, if you were pregnant, so gives similar symptoms.

thank you so much for your help, I guess you hear this often but I'm still gonna say it anyway, thank you thank you. Even my boyfriend thanks you lol (whenever I freaked out, he kept referencing your comments and it definitely got me to calm down).

I actually got my period just now (after my comment from earlier today) and it started off super light so I thought it was a fluke. But then tiny clots started coming out and I can say that I definitely feel better than I did these past couple days. Still have the pms symptoms tho but it's okay.

You're very welcome. To be honest, most people don't bother replying, never mind saying thank you, so I appreciate you saying it. I'm please you got your period. No doubt a huge relief for you. It might be a bit different to usual (heavier/lighter/longer/shorter/pinker/redder/browner/clottier etc), & you might still notice some more hormonal side effects over the next few weeks, but don't worry. Things will settle down and get back to normal in the next month or two, if not sooner.
It's only some women that wait months for things to straighten out again, & it sounds like you're already getting there.
