ttc after miscarriage

the beginning of this month i had a chemical pregnancy. after the bleeding/period stopped (1 week later which is abnormal for me) we started ttc again. dont know exactly when i ovulated or if i even did so we just had sex a lot this month lol. my question is, is there anyone who got pregnant right after a chemical pregnancy? was there any complications? does the chance of multiples increase? we're hoping my period doesnt come next month but idk if its possible to get pregnant RIGHT after a chemical.
