Advice please 1st pregnancy

An

So i got my positive today and when tl the doctors here in dubai. Im roughly 16 or 17dpo. The picture is blury but alot more pink in person. I took another one but this was outside the time frame so i guess that doesn't count. I can post the pic if necessary . She said the line is weak so requested beta hcg. My concern is would it show in my blood at this stage🤷‍♀️
