Chemical pregnancy , please don't judge

Ni

I found out I was pregnant on the 16th of March (HCG:70) and then found out I was misscarring on the 18th of March (HCG:34) , then on the 21st , i went to the hospital again (HCG: 12) and was told then that i was only 3 days pregnant on first my visit. This all started on the 13th when I started bleeding brown, then bright red until the 19-20th. Idk how to feel cause I'm blessed I wasn't too far along but then again I'm also hurt cause my fiance and I have been trying for 5 years , we found out , then it was just ripped from us right after . Was this a chemical pregnancy ? Should I feel stupid for only being 3 days pregnant and being so hurt ...?
