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

As you can see by the many comments in this thread, ECP can cause your period to be late. A pregnancy test is recommended if your period does not come within a week of its expected date, which you did.

There is nothing to do but wait. As you can see by the many comments in this thread, ECP can cause your period to be late. A pregnancy test can give you peace of mind. They are accurate 14-21 days after sex.

I had sex with my gf within a 3 days period and she took postinor 2 for the first and second day all within 24hrs but didn't take on the third day since I didn't ejaculate into her and after 3 days she started bleeding. Now she was suppose to get her period on the 15th of May, 2018 but it hasn't come and her breast is tender. please is she pregnant?

My girlfriend and i had sex with condoms thrice in a week..
And she took postinor twice .
Now she hasn't seen her period for days now...the previous month she saw her normal period.the next week in that same month,there was some slight blood flow which was abnormal.
She has used the PT strip test twice but it came out negative ...it's been about 5 days and she's missing her period.
What could have happened?
I need help urgently..thanks

Why did she take Postinor? Unless there was condom failure (which you did not mention) taking ECP unnecessarily only disrupts the menstrual cycle. A woman's period can be early or late as a result. This is likely the case for your girlfriend.

Hello Helena,
I would appreciate your help since my case is pretty weird. I had unprotected sex in the morning of March 10th when my period started on Feb 28th and finished on March 6th. I took Postinor 2 within 24 hours and it started to bleed on Mar 16/17th for a week like normal period. The problem is I’ve had dizziness since yesterday (with fever) and a little bit of cramps today. I was not worried after period until yesterday but now I’m freaking out. Could you please help when should I expect my next period?

Thanks a lot in advance

We cannot predict when your next period will come. If you bled for a week after taking P2, it's unlikely you would be pregnant. Still, some women don't believe this and prefer to take a pregnancy test even so.

Fever and dizziness would not be related to your period. You may be coming down with a viral infection of some sort.
