Am I having a chemical pregnancy?

Kayla • Wife & mama raising two babes with my angel baby Ada in heaven. ✨ 10/3/2020 Rest In Peace my beautiful baby girl. 💖

The first day of my last period was January 12th. It lasted until the 14th with spotting on the 15th. I am getting positives along with an HCG level of 26 as of today. The only symptom I’ve been having is heavy/sensitive breasts. Either I am very early on or am I experiencing a chemical? I’ve never had one before so I don’t know what is going on. My doctor couldn’t give me a very good answer either besides that I have to go back in on Monday for another HCG draw. I am devastated. We lost our baby girl at 9 days old in October. I was so excited to find out we were expecting. 😔💔
