Is that an early sign of pregnancy? I have gas, Tiredness, burbing and get this nasty taste in my mouth, like vomit, but i never vomit. Some cramping, but light. I just came of the depo shot, but i only took one shot for 3 month. My period was on for a month and 1/2 on the 3rd month and went off. Two weeks later i bleed for 11/2 day and it went of. That was almost 2 weeks ago and now i am getting these symtoms. I will test if i don't get a period on 17th. I feel horible.
