I recently found out I’m pregnant about a week ago now. I went to the ER to confirm and had minor back pain. They did hcg bloodwork and it was 218! They did an ultrasound and couldn’t see anything. They even checked for an ectopic and didn’t see anything. I followed up in 48 hours and the dr told me my levels dropped to 136. He said it could vary from lab to lab. Other than minor back aches I feel fine. Has anyone else experienced this? What was the outcome?
