is this true

Rachel • Wife/Mom to my 9 year old boy, my 3 year old boy, and 2 year old baby girl

I have a question, I had a miscarriage between April 9th and the 16th. lately my boobs have been hurting and I've been eating more often than before. is there any odds that I still had hcg in my body or could this be I'm pregnant again? Mind you this positive showed up kinda quickly
