I got a definite faint 2nd line this morning a week after my expected period date (pictured below) I called my OBGYN and she ordered a blood test and it came back with the HCG levels at 18.8 is is that normal? I know when you're not pregnant it's under 5. My doctor hasn't talked to me yet so I don't know what her game plan is. I had a miscarriage in August so I'm just worried cause this is my first baby. I feel like the levels should be higher...
