7 weeks in 2 days

In 2 days I will be 7 weeks pregnant. My first ultrasound is on the 13th. I'm a little nervous. I want to have a natural childbirth if I can. My moodswings are driving me nuts though. Since I'm pregnant I can't take Prozac anymore so it's difficult to control the moods like I used to. I've only puked once but I get nauseous every morning and sometimes even as long as into the evening. My sleep cycle has been way out of tune as well. I feel bad for my fianc though he has been a loving, supportive, and understanding man through my mood swings and disinterest with sex. I don't know at times if I'm more excited or scared about this child. It seems unreal to me. It might seem mores once I have my first ultrasound. I'm working part-time at the very least but it is becoming a bit more worrisome when I think about finances. Things will be tight. I love my developing baby, I want to give him or her the best life... I just hope I am a good mother.
