Am I?

So I am worried I might be pregnant. I'm having similar symptoms like I did with my first child. I feel upset because I don't want a child right now. Not that I wouldn't be happy or excited if I am. I just moved to NY to be with my husband and I haven't taken any bc because I was simply not having sex. So now I'm here in taking it but I feel now it might be pointless. I'm looking for schools to go to out here for Nursing. I want my career first. Just Scared... I want my dream to come true. :-( I know a life is so precious so either way just have to make it work.
