Sitting in the ER

Sara

Sitting in the ER waiting for ultrasound results due to light bleeding with small clots and light cramping. Due date is to be March 14th due to last period on june 8th and pregnancy test taken on July 14th. Please explain to me how my hcg levels and ultrasound put me at 5 weeks? I'm so confused. They also gave me a rogam shot due to bleeding. Wtf is going on? I'm freaking out. It's only been 4 hours.
