Am I having a miscarriage or not?

Okay so to your hcg numbers are to low for anything to show on a ultrasound so thats ruled out why everything looked normal...they should do another blood test to see if your numbers are doubling or dropping etc..I am no dr but my thoughts on this is that you are pregnant but not as far along as you think thats why the test you had a week earlier was negative ...Try not to worry i don't think your having a m/c and not being harsh but theres nothing you can do other than get another blood test for numbers and or ultrasound in a few weeks...hope all goes well
