Ok before I found out I was pregnant I weighed 183 lbs I was working on losing weight because when I left my ex husband I got really depressed and wouldn't leave the house and the only food I would eat was junk. So I went from 160 to 210. Anyways I haven't been to the doctor yet and because of my periods being weird I don't exactly know when the first day of my last period was. I do believe I had one in January so I'm pretty sure I'm somewhere between 6 weeks and 9 weeks at the most. But if you look at the picture I look so much further. This is kinda bothering me. I know when I was pregnant with my girls I gained a lot of weight. My finance is also a twin so that's a possibility but i just wanted to ask if anyone else has blowed up like this? Thanks
