What is wrong with me? My first trimester was horrible. I was sick constantly. Then my 2nd was a lot better and now that I'm in my 3rd I feel like crap all the time, I can't even get dressed or take a shower without running out of breath. I don't have an appetite for anything anymore. I'm constantly tired and my back is constantly hurting. Like why??? My first pregnancy was so easy and I loved being pregnant...shit as soon as I pushed him out I said wow that was so easy I could do it all over again! Plus my pregnancy was just awesome! No complications or anything! But this one...ugh I just want him here so I can feel normal again! I could of sworn I was going to have a girl just because of how different my pregnancies are. But nope another boy 6 years later lol 😊
