D&C questions

Isir

Hello ladies, I had a d&c back in Aug.20 and I was 13 weeks but fetus was only 11 weeks. Oct. I had a faint line on a pregnancy test. I don't know whether it was a chemical pregnancy or just hormones lingering from my DNC. Nov. I had another faint line. I have been trying to get pregnant this month, I am 9DPO and I just got my period. Please help and how long does it take for the body to come back to normal after a DNC surgery?
