11 months no Luck, taking break

I thought for sure this was gonna be out month af was even two days late. But af showed her ugly face this moring. I just don't understand it. I had the implant in my arm got it taken out went on birth control for right after bam that December I was pregnant two cycles on bc pill. Had my little boy in aug 2012 and we have been ttc since my husband returned from oer seas and still nothing. I use opks, preseed, lay afterwards, take prenatals the whole nine yards and still nothing. :/ I think I'm gonna take a break.
