Absence of menstral cycle

[jessco]

My husband and I have been trying to have a baby since May.  I was on Levora (birth control) and went off of it in April.  For the first few months April, May, June, July...my periods were irregular, which is to be expected, since I went off of the pill.  They SEEMED to be regualar in Aug. Sept. and then in October, I didn't have a period.  I wasted so much time and money taking pregancy test (blood and otc) and no pregancy.  In November on the 6th I got my period, but it only lasted 3 days and was very light.  Now I counted 28 days from that, which is the length of my cycle the pervious months minus Oct. and my period should have been due on Dec. 4th.  Here it is Dec. 12th and still no sign and I don't even feel like I'm going to start my period.  I keep getting what I would say are Hot flashes and not to sound gross, but my arm pits are sweating really bad and I've been taking showers 3 times a day.  I also have started to grow hair on my left breast.  I don't even know what it going on.  Is it an overload of testestorne?  I'm not taking any medication.  I take a One a Day Womens vitamin.  I'm not under weight.  I'm 160lbs.  and 5'6".  I'm very healthy and I exercise...4 times a week...although I should be working out 5.  I took a pregancy test 2 days ago and it was negative. Please help and give suggestions.  
Thank you!

I should clarify.  I do have one child...who is 4.  I've been through pregancy once and had to be induced.  I did have an infection in my uterus from the breaking of bag of waters I'm guessing and was put on antibiodics for a month...vaginally and oral.  I also had a colposcopy done about 2 years ago.
