Morning after pill

Me and my partner had sex and the condom broke I didn’t take the morning after pill Till 24hrs after sex. Its been a week and iv woken up to bleeding and in so much pain, my periods are very bad but this is just awful😣. I’ve taken plan b before and my period wouldn’t show up until two weeks after taking it. So I’m abit confused 🤷🏻‍♀️ I ovulated either the day before we had sex or the day we had sex so I’m worrying as I know it didn’t prevent me from ovulating or delaying it. Has anyone ever fallen pregnant and took this pill? Also has anyone ever bled 6 days after taking it.
