I am kinda on the same page with you. I am 23 weeks but I feel like I am huge and I am just kinda....Well, pregnant. The first time I was preggers I was very happy the whole time until I got sick and was put into the hospital. But with this one my whole pregnancy I have been just blah. I was really sick for like 3 weeks straight and couldnt' go to work. Then I was late every morn and now I am so tired all the time I can't hardly think. I have other issues that really don't have anything to do with pregnancy but that take affect on me and the added stress of other things other than pregnancy just doesn't work for me. It seems that since I have become pregnant the whole roof is caving in on me and there is nothing I can do for it because I am pregnant.
I don't know if this is the same as you are feeling...But I got some pills from my doctor that will take the edge off. I filled the rx but I haven't takin any because I am unsure about it.
Just try to relax, I know easier said than done....Believe me I know.
