I posted my ultrasound yesterday with excitement, but now I’m freaking out. The first day of my last period was March 13th. My average cycle length is 31-32 days. I didn’t get a positive pregnancy test until April 19th (about 5-6 days after expected period). My HCG that day was 20. So very early. My HCG went to 127 4 days later and then to 517 3 days after that. I went in yesterday for an ultrasound expecting not to be 8 weeks like this app and every calculation says, but now I’m concerned. My ultrasound measured 6 weeks 1 day and heart beat was 120. My husband wanted to tell just our parents on Mother’s Day, but now I’m scared. I’ve read soo many stories about miscarriages on here and other sites. Thank you in advanced for your help.
