I'm trying to stay positive but it's so hard right now. The last two days I have been hurting so bad in my stomach area and down in my Virgina. I try to sleep but always end up waking up cause the pain. Not to mention my knee hurts like a bitch and I can barely walk. L&D said yesterday for me to be on bed rest but my grandma and I got into an arguement so I left and came to my moms. At this point I just wanna go home and lay in my own bed and relax and take the bed rest like I'm suppose to but my mom is sleeping and can't take me now. I can't help but feel I'm being a bad mom and something isn't right but I have never been this far pregnant so I don't know what's "normal" aches and pains and what's serious aches and pains.)":
