Now for the past week or so I have been feeling sick in morning and late at night mood swings out the world. Heart burn and to me it feels like I have gain weight my waist trainer isn't fitting. I am an over weight 220lbs. Could I be pregnant or its all in my head, I have a 7 year old and did not know I was pregnant with her I did not get any pregnancy symptoms with her. So I'm just scared because a lot of women said they gotten pregnant while on this please help me with your advise
