After 2 mc in 2015, im FINALLY pregnant

Jessica

Hoping and praying for a healthy 9 months... today i go for my first ultrasound and im a bit nervous after what has happened in the past..

im a bit confused on how far along i am because my last period was june 3-6. Was testing negative, got a negative blood test july 18.. re did blood work july 26 and my blood work came back POSTIVE,

Any idea if they would count it from missed period or when i got my postive??
