It is unusual that Maria hasn't gone into her first heat at her age, and it's possible that she has had a heat but it was a silent heat. I'd recommend a check up with the vet for this problem. It would be rare if she was born without a uterus, but it could be possible. Only a vet can diagnose this. I'd make an appointment for her this week. I hope this helps!
