anyone ever heard of being pregnant but have really low hcg levels?

@butterfli_luv, baby dust to you

Im at least 6 weeks because my last period was mid September. I had light spotting(pale pink) on Oct 1. @butterfli_luv you set my heart at ease

last tested my level was around 6. I just got my first positive. I go Thursday for a sonogram. my Dr has calculated me at 6 weeks. but my levels aren't as high as should be she said its common but it scares me.

What are they at if you do not mind me asking

could be very early on in pregnancy but your levels should almost double every day
