Hi,If you have not been doing anything to avoid a baby you should have conceived.However,not to worry,please make an appointment with your doctor for a detailed history and scan on the second or third day of your menstrual period.A scan would be normally offered and should give a fair idea on your uterus,ovaries and your ability to produce eggs.As you are fairly young and if the scan is normal,you probably would not need a hormonal evaluation.If you are keen on a baby,I would also ask your partner to get a semen analysis done and a tubal evaluation for you.Hope this helps.All the very best.
