Baby Appt today

I have an appt with my ob today at 3:20. I am hoping everything goes great. I am 6 weeks today according to O. I still do not have a set due date because i was too early on my last ultrasound. My next ultrasound is next wednesday at 7w2d. i can not wait! i just want to know baby is okay and the heart is beating away. i am itching to buy pregnancy books and breastfeeding books but i don't want to get them and have them laying around the house if i miscarry. I am still very on edge since the bleeding episode i had last week. Anyway, I will update once I get home from my appt. wish me luck!
