could i be????

so i have no idea what to think..... my periods have been messed up forever anyway, and i was on birth control for about 3 months (i was going every 2 weeks).  the bc got me straightened out, and i stopped taking it in august. i started going every 2 weeks again but they siad it could just be coming off of it.  well i know it has been 3-4 weeks, and maybe longer since my last period, i dont remember, nor do i know if i should consider a 1 day blottting as a period.... anyway, i am exhausted all the time, and have started some vomitting again.  i am a little over a year out and have lost 165lbs.  i was told i prob couldnt have kids on my own when i was big, and i never knew when i actually ovulated.  i have had a rough year ( i was just a year out at the beginning of oct), but thought i had been doing better.  all my bloodwork, hormone levels and everything had been fine when i was at the dr a couple weeks ago..... but i just started vomitting more this week *i went thru a lot of vomitting with an ulcer, but had been doing a lot better+ and right now things are sounding good to me that i usually dont eat a lot of..... like lettuce and chesse and crackers..... i want it for every meal!!!! maybe it is just in my head i have just never went thru this nor thought it a possibility....... anyone have any ideas?

Well- you have come to a spot where most ladies are POAS (pee on a stick) addicts- so most will probably say get a test.  I agree- in the scope of issues there are certainly dollars well spent.  I say buying a test is worth it.  I was told for many years I couldn't have kids and one even told me flat out he wouldn't assist me with having kids- until I was healthy.  A year out, pregnant (I was trying).  So- all the years I battled infertility apparently are over as long as my body is healthy, I can conceive on my own.  1 day of spotting could be implantation bleeding, some woman bleed enough they believe they aren't pregnant....  I got positives with dollar store tests...but the digital pregnant or not pregnant are nice for a no guessing lines kind of answer.  I had horrible issues during my first several months, ulcers, bad GB, bowel obstruction, adhesions...but I cant say any of them felt like pregnancy issues (okay maybe the vomiting issue, I have had that once or twice with my pregnancies post op).  Usually health issues made me not want to eat...pregnancy does the opposite to me.  YIKES!  Good luck for the outcome you desire and let us know.

i feel like i have been eating nonstop..... and wanting too, everything sounds good, just not been able to keep it down....and i have been very emotional and my nose is very sensitive right now.....
