OK, I stopped taking the Depo injection in Dec. of last year (2012) and began my cycles back up in June of this year (2013). I have had them regular cycles every 28 days 5 days long since; however, my last cycle in Aug 30th lasted 7 days not very heavy an average flow. Well, now I was due to start on 09-27 and nothing I do have lower abdominal cramping like if i was about to start, but nothing. I've taken an hpt test today which is 8 days late now first thing this am and negative. I have dry mouth, low back pain, and extremely tired (I thought it was all the meetings at work i have attended). My stress level is about normal a little more than usual and no recent changes in my everyday schedule. I will admit my partner and I are ttc so I was upset this am when i saw the negative result, but I know that what i've been feeling is different with my body here latley. Please any advice is it possible i am pregnant and test too early?
