"Plan B" pill - need an advice

[Marika55]

Hi,
my problem is delayed menstruation. Last period appeared 25.09. I've had sexual intercourse on the 9.10. and due to condom burst, I took morning-after pill called EllaOne (exactly 4 hours after this misfortunate happening). 3 days after taking this pill had unusual, brownish mucus, but only 1 day.
I've waited 2 weeks in order to make the pregnancy test from store and the result was negative. Being concerned with lack of period on October i went to nearest hospital for beta hCG test of blood to be carried out (was about 1 month after having an intercourse) and the result was =<0,100 mIU, which would indicate I'm not pregnant.
Why am I not having period on time? It's being already 52 days since my last menstruation. May I exclude the possibility of being pregnant? Or is it the result of EllaOne?
I'd like to add, I've never had any problem of gynecological source, neither I was using any hormonal contraception.
Please, help me. I feel hopeless, I'm very stressed of being pregnant...

Your blood test is so low that there is no possible way that you could be pregnant this far removed from the initial rendezvous and if you look up information on Plan B, you will find that those fall under listed side effects. It's a large dose of estrogen which throws hormones and you cycle all out of whack. I promise, you're in the clear.
