Is there a reasonable chance for me to conceive while still breastfeeding my fifteen month old baby? my cycle is regular and i ovulate.

Breastfeeding: Yes, you are able to conceive so use protection, unless you'd like to have 2 kids in diapers at the same time.

Yes. : Yes you can get pregnant if you are sure you are ovulating. Checking with an ovulation indicator kit to tell you when in a particular cycle you ovulate will also increase your chances. If you decide to stop breastfeeding you may also increase your chances as you will more likely ovulate more consistently.
