Thanks for your query. The pregnancy rate
of Condoms is 3/HWY, hence you could be pregnant. Get a UPT done and get your doubt cleared. As your baby is 10 months old, its better you go for OC pills or get inserted a Copper-T, only after consulting a gynaecologist.
I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow ups.
Wish you good health.
