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

What is I2? Do you mean Postinor 2? It can cause irregularity in your cycle. Some women get withdrawal bleeding after ECP, some do not. It's recommended that if you don't get your period within a week of the expected time, to test for pregnancy. So, you should do that.

Hi there,

I had my period on 16apr-24apr

After that I had unprotected sex on 11may and I took postinor on 12 May and one tablet 13 hours later.

However, after that I had unprotected again on 12 may and 13 May.

On 18 May I had my period which lasted until 27 May.

And on 31st may, I had my period again until 6 June.

On 24 June to 28 June I had some extremely extremely light brownish spotting. But it's not even blood at all.

Could I be pregnant? Because I hadn't had my period for whole month of June, but I've Been experiencing cramps since June 23.

Pls help!

Having your period was proof you are not pregnant. If you doubt this, test for pregnancy. Your cycle should go back to normal with the next period. If your periods continue to be irregular (where they were not before) See your GYN.

ECP can cause irregularity. If you had your period previously, pregnancy shouldn't be a concern. You can always test to ease your mind if you are still worried.

You are not using this medication correctly. It's supposed to be used as emergency contraception only. In two pill dosing, 1 pill is taken as soon as possible (and within 72 hours), and the other pill, 12 hours later. You don't keep having unprotected sex and taking more pills. You have likely caused a hormonal imbalance by taking too many pills. Call your doctor for further instructions.

The light bleeding is withdrawal bleeding - typically indicating the pill was effective. However, it's advised to test for pregnancy if your period is more than a week late. ECP can cause a delay in your period and may change the flow when it does arrive, so keep this in mind.

We had unprotected sex on 25th May just after 6 days from periods (Due 19th). After around 10 days there is another period happened. So seems all went well.
But problem is this month cycle is late till today (11 days late) which is confusing. Do we have a risk of pregnancy?
Pls help
