Brown discharge after PLAN B and for next period??

[worried1010980]

There was a questionable incident on Oct 26.  I took plan B about 60 hours later.  About a week after that, I had very light, brown discharge for several days.  Last week, I should have gotten my regular period and I did not.  I have taken about 5 pg tests since the incident which was now 4 and half weeks ago.  The incident happened several days after I ended my last period.  The last pg test I took was this past sunday.... which was 28ish days after the incident....  They have ALL been negative.  I do not feel pg and have no other symptoms (although I do have PMS symptoms).  I have read that Plan B can mess with your cycle but I have taken it before and have not ever had this happen.  I am worried because now, when I should have my regular period again, its still the light brown discharge barely enough for a liner (same as the week after Plan B).  Im paranoid because I DO NOT want to be pg.  Has anyone else had this happen with Plan B?

Would a blood test show a positive result at 5 weeks?  Ive had a negative blood test before when I actually was pregnant.  Also, I read a lot about people getting ultrasounds early on... how do you get the dr to do that?  I want to know FOR SURE 100% either way asap.

Can't personally say I have, but I've never used it. Plan B is a massive dose of hormones and can cause different reactions, even in the same people or those who have used it before. What you've described is typical responses to it. You can talk to your doctor about it and see what they say. They can also do blood testing to check for pregnancy. I would also strongly recommend a more reliable form of birth control and/or condoms so you don't have any more. While Plan B can be good for BC failure, it only has an 85% success rate and has been known to fail.
