Freaking out!

Lauren โ€ข Our second daughter! ๐Ÿ‘จโ€๐Ÿ‘ฉโ€๐Ÿ‘งโ€๐Ÿ‘ง EDD 8/8/2016 ๐Ÿ’•
Got 8 positive (faint, but clear) HPTs so went to the doctors. Negative doctor urine test so he ordered a blood test. Results came back bhcg at 38. I'm currently 15 dpo. My period is 1 day late (average 28 day cycle) Is this level bad? I'm starting to freak out. Took another HPT today and the line was darker than it was a few days ago but just worried that 38 is low. Anyone else have a number like this??ย
