Went To The Doctor Today And Had A Ultrasound Because

Went to the doctor today and had a ultrasound because I am supposed to be about 9wks pregnant, nothing is showing up on the scan. Hcg Levels say pregnant. Doctor says I am having ectopic but they don't actually see a baby.....she called a technician in and technician found a "mass" on one of my ovaries, but from a previous er visit I know I have cysts on my ovaries. Tomorrow morning they want me to come in and terminate the pregnancy since they cannot find a baby and see a mass....I have read about many woman who see nothing on scans but end up having normal pregnancies and healthy children....is my doctor rushing it..should I wait and hope my baby shows itself?
