Pregnancy Info HOME

Well i just found out that i am 4 1/2 weeks pregnant. While this should be a very exciting time i have some major concerns. I thought i was having a period a week ago. I had bleeding and cramping just like a period. I had to use a tampon for a few days but there was no significant bleeding or clotting. I went to the doctor today and they did some blood work and an ultrasound. The ultrasound showed what could possibly be a sack and measured to be the size of a 4 1/2 week but the doctor said it could also just be stuff left over from a miscarriage. Has anyone ever had these symptoms and continued on with a healty pregnancy?? I have to go back for more blood work in two days to see how my levels have changed and to find out for sure what is going on? Let me know what you think..
