Quarantine baby! Excited but scared

Ciera

Had my period on April 18th. It was gone by the 24th. Fast forward to Sunday the 26th I began spotting. I knew something was wrong because years ago on my first and second pregnancy I had spotting after periods and had a chemical pregnancy and ectopic. 2018 was a normal miscarriage. Anyways Monday the 27th took a digital test and it was positive. I went to the ER and they did blood work and I had an Hcg of 36. By Wednesday it doubled to 72! So far so good. Tomorrow I have to get my levels checked again and hoping the baby is continuing to grow. Has anyone else had a normal pregnancy after a period then spotting?
