Doctor :   Hi
Doctor :   Can you tell me which hormone are you talking about as there are many pregnancy hormones
User :   The HCG , i am pregnant and my pregnancy hormones level is at 87 and im not sure how many weeks i am
User :   the HCG
Doctor :   When was your last menstrual period?
User :   in feb or january im not sure
Doctor :   Ok, just with the level of HCG in the blood, we cannot judge the week of pregnancy
User :   87 HCG
Doctor :   So next way to go ahead is by Ultrasonic estimation of the period of pregnancy
User :   what do you mean by that
Doctor :   I mean, you go get a Scan of the abdomen, the radiologist will be able to say the exact period of pregnancy by certain parameters
User :   ok
Doctor :   The serum HCG level of 87miU/ml suggests about positive pregnancy
User :   is the fetus of the baby
User :   is it the fetus
Doctor :   yes
User :   is that week 3 of the pregnancy and HCG 87miU/mL
Doctor :   Are you getting my messages?
User :   yes i am
Doctor :   According to American Association of pregnancy, the normal HCG levels at around 3 weeks is 5 to 50 miu/ml
Doctor :   but can increase to 400mIU / ml
Doctor :   by 4th week
Doctor :   So it is definitely not the best way to judge the age of pregnancy with HCG alone
User :   so im past nearly 3 weeks pregnant
Doctor :   The best way adopted by clinicians is by Naegle
User :   alright
Doctor :   Last menstrual period + Ultrasound dates
Doctor :   That is called 'Dates Scan'
Doctor :   Hope I have answered your question
User :   do i need a referral for an ultrasound
User :   yes u did
Doctor :   But that is part of routine investigation at 6 to 7 week of pregnancy
Doctor :   So next time you visit the doctor as part of antenatal check up, she orders few labs and an Ultrasound
User :   ok thats alright
Doctor :   Do you have more questions that I can help you with?
Doctor :   Are you with me?
User :   no i dont
Doctor :   Pleasure to assist you here
User :   ye i am
Doctor :   Thank you
Doctor :   Bye
