So I am 3 months and happily pregnant, however...I'm having some ungodly pain.

So this is what I think happened. I am a working woman and I work in a factory doing heavy lifting and staying on my feet for hours, i can be working anywhere from 8 to 10 hours a day depending on how busy we are. Where I work I am required to wear jeans. When I became pregnant and found out we had little money and couldn't afford to buy me any new clothes yet. I had to go to work wearing really tight jeans and i felt like it was poking me, at first it was just annoying and then it became painful. By the time I got bigger more comfortable clothing I had these sores on the bottom of my belly right before my bump where my pants would sit. They hurt, but I would put bandaids on them and what not. But then the sores got worse and turned a darker color and some of them turned into bumps. Now it hurts so bad I wake up in the middle of the night crying because the pain and I can't sleep. It hurts to move at all. I went and got triple antibiotic ointment, hospital grade gauze and a wrap and applied all to my stomach. And it feels a bit better but it still hurts sometimes. I'm not sure what it is. I know I should probably go to the doctor...but I would just like to know if anyone has had this problem and if they know what I can do until then. Thanks all. :'D
