Tough Situation

Maria

So I found out today that I am 5 weeks into my pregnancy from a man that I met 3 months ago. We had an accident so I took the Plan B but it did not work. I am very emotional. I don't know how to act towards him but he's trying to be supportive. My mood swings are so back back and forth... sometimes I want to talk to him and other times I don't even want to hear his voice. I feel like I am going crazy. Is this normal?
