did bloodwork today and scared I may be having a miscarriage

I'm very unsure what my due date is due to irregular periods but I did bloodwork today and my levels are 459 by calculations I'm about 4-5 weeks pregnant is that a normal level I go back for more bloodwork Thursday? ? Also my legs and arms have been going numb alot too :(

It's normal and should double by your next blood test. Good luck.

Thursday when I rechecked levels it was 867 I go back tomorrow to recheck hoping everything is Ok :)  

Levels last Thursday were over 13,000 go tomorrow afternoon for my sonogram asking for prayers that everything is Ok and the baby is healthy :)
