Hey so I found out on the 15th that I was pregnant from multiple tests, I know it’s way early ? Well I went to the hospital last night for an abscess I had they did an ultrasound and couldn’t see anything so they did a blood test and my hcg is at 77.09 is that normal ? They also said it could be way to early to see anything on the ultrasound
