My period is late after taking Postinor 2

I was on my 6th day of my cycle (just finishing my period). The condom split so I took the first tablet of postinor2 2 hours later (1am). We then had unprotected sex 6 hours later (7am). I took the 2nd postinor tablet 3 hours later(10am).
8 days later I had heavy bleeding lasting 4 days. Firstly, is this a sign that postinor worked?
Since then i have had no sign of my period.
In the last 2 weeks (aboit 22nd day of cycle) I have had the flu and been unwell. This has all made me quite anxious.
My period cycle is quite irregular.
Thanks for your help in advance

Hello deedratic
You were already helped on this topic - your period is delayed due to taking P2 -it can be delayed for a few weeks. You have to be patient.

Hello please help me out
I have unprotected sex with my boyfriend during the last weekend. I supposed to see my period on 26/01/2018 ie last week Friday. So I had sex that the same Friday, Saturday and Sunday morning. I took postinor 2 on Saturday night by 12am.
Up till now I haven't seen my period. Please what could be wrong?

Postinor 2 can cause a delay in your period. You'll just have to wait it out. If there is no bleeding with 3 weeks after taking the pills, test for pregnancy. Keep in mind, emergency conception should only be used for emergencies.

Hi, I had unprotected sex with my gf but I did not ejaculate in her and this isn't the first time, I normally get for her Postinor 2 the single dosage andwe never worry but this time it only had the two tablet dosage,, she took the first one about 20 minutes after we had sex and the other was supposed to be taken 12 hours after or 16 hours for the latest. She felll asleep and took the second tablet exactly 16 hours after, I've read different forums that once the first is taken before 12 hours the pill will work and some peoples cases are more Serious then ours and it worked for them , the second can be taken same time, but yes she took the first one in perfect time and the other 16 hours after I know that the pill will work still but she is worrying and when she is worried it worries me, yes a chanin effect , but I want to know will be okay and not get pregnant? I definitely know I did not finish in her and she too the first tab. 20 mins after and the second 16 hours after so if anyone can help me out that will be perfect , thank you all so much

The pills will likely be effective, even if the 2nd was taken later than prescribed, but we can't know this with certainty. If you didn't ejaculate inside her, there is no pregnancy concern. For future, these pills should not be used as a regular birth control method. They are for emergencies, such as an unplanned sexual encounter or birth control failure. Overuse of these pills can cause hormonal imbalance. Condoms can easily be used instead.

Hello Anon
A delay in periods is common after taking P2. You are not pregnant - your period will be along when it's ready.

I had unprotected sex a day after ovulation,(going by the app) took Postinor 2 and inbetween the first and second dose we had sex again. It’s time for my period and I am 3days late. Kind of worried.

Hello Anon
A test would be accurate by now so if you take one you will know for sure. Your risk is low.
