Question
I am Jihan Yehya, a newly married woman, who knows very little concerning pregnancy, and methods to try to get pregnant!
Thus, i am sorry in advance if any of my questions sound a little bit outgoing or if my story is too long.

Me and my husdband have been trying stay away from pregnancy at least for our first year of marriage. Our relationship was on the 14th of November, and my period was on the 6th November and ended on the 10th of November. Unfortunately, I have been taking Norlevo (much like plan B one step, as it contains 1.5 mg of  Levonorgestrel) for the past two months a lot. I took about 5 pills, on different occurrences in the last two months, and my last was on the 14th of November.
I have noticed the shifting in my period timing and the amount of bleeding, that the last bleeding i had was on 28th November, for 3 days and it was brown blood that made me think its implantation bleeding!
Last Wednesday 14th December (after a month from the relationship) I did a blood test and the result came out as 0.1 mIU/mL). My last test was on 19th 5ecember on Monday, a urine test that came out negative. I have no pregnancy symptoms, other than the period shifting and amount.Do you think there is still a chance for a pregnancy???
Thank you!

Answer
You're not pregnant from sex on November 14, as a pregnancy test will be positive 2-3 weeks after conception.  It's common for plan B to cause irregular bleeding, especially when it's taken on multiple occasions.  I would recommend using another method of birth control, since plan B is designed to be use as emergency contraception.  The regular or minipill would probably work well.  There is more information on birth control here http://www.plannedparenthood.org/health-topics/birth-control-4211.htm
