Okay so I took a pregnancy test last night and it was very much so positive. The problem I am having is I haven't had my period in over a year since my first child was born last year. So I have no idea how far I am and if the baby is okay. So I am freaking out a little and trying to think if I have done anything stupid recently that could have hurt the baby... Help me calm down please!
