<s>[INST] So when i was 3 i was diagnosed with growth hormone defciency and i took daily shots in my stomach until i was 14 and my doctor said if i didnt get my period by 16 i have to go back and see whats wrong. i am 16 and still no period. so i was wondering what could be wrong? what tests they will run? if it will be awkward? if its normal? ya know just so im not freaked out about this! ps.. i really dont like going to my doctor. its a guy and i just think its awkward talking about period stuff. [/INST] Thank you for posting your query in Chat Doctor .com.....see first, talking to a doctor about anything is not awkward....but for proper diagnosis and treatment, you should tell your doctor everything...anyway, primary amenorrhea is said to be present when there are no periods and no secondary sexual character at age 13 or no periods but presence of secondary sexual character at age 15...so irrespective of your secondary characters like breast growth, pubic hair etc. you are suffering from primary amenorrhea....well there are various reasons behind primary amenorrhea, most common being genetic and uterine developmental defects...so in my opinion, you should definitely visit your GYNECOLOGIST and he/she would run some tests like USG, laparoscopy or hysteroscopy and might be karyotyping also depending on your features...also definitely some hormonal studies also....it might not be very serious till now, so don't worry but visit your doctor immediately...hope this was helpful....come back to me for further queries...regards </s>
