The amount of time it takes for a woman to conceive another child after giving birth varies from woman to woman. Breastfeeding can also delay conception.
The general practice is to begin a medical evaluation after a couple has tried to conceive for one year without success, or after six months if over the age of 35.
While it can be scary and overwhelming to enter an unknown world of tests and procedures, the fact that you would be thrilled to get pregnant may be an indication that you are ready to look into the matter. When and if you want to proceed, you should raise this concern with your gynecologist. Take things one step at a time. Do not overwhelm yourself, and wait until you feel ready. Your family planning is a private matter between you and your husband, and you can choose with whom you wish to discuss it.
You may also find it helpful to consult a Yoetzet Halacha Fertility Counselor. (This is a free service, details here.)
