Ok, so I used to be on birth control but stopped taking it back in Septmember, so it's almost been a year since I stopped it.  I used to be on the longer end of my cycles, but once I stopped the birth control I was always around 30-34 days.  Then in January I started to be more like 42-47 days range.  I'm now at day 54.  2 weeks ago, I thought I was getting my period but only had some dark pinkish spotty for maybe a half hour, then it was gone.  The next day, I had spotting in the afternoon, but it was brownish and thick and then once again, gone in an half hour.  I used to only getting spotty while on birth control and haven't spotted for quite a long time now.

Now the big factor leaving me confused out of my mind, the guy I've been with for almost 2 years can't have kids because he has a vasectomy (so obviously, no protection used), so what's wrong with me then?  I really didn't start being bothered by it til today, so it can't be the stress of thinking about it.  Also, for the last week or so, I get nausea in the morning, probably within an hour of being up, then feel better, then back around noon and again at night.  Just about everyday, same thing but never threw up, but haven't been able to eat because everything has been grossing me out. Also, it feels like I still have here and there cramps.  I find it hard to believe I really could be pregnant, so any ideas what elese could be wrong with me? 54 days as a cycle seems crazy, that's almost twice the normal cycle for a women.  Also, I'm 28 so I don't know if the age has anything to do with it. 

Someone please give me some thought.  Obviously probably have to go to my OBGYN, but anyone ever go through something similar?
