I'm 9 days late on af.... Taken a few home test the first week of missing.... all negatives.... Went to the health department yesterday and got a negative on my blood test.... The lady asked me to come back in a week and take another just incase because my levels weren't high enough to consider positive.... What does this mean? Can/should I continue home tests every few days just incase? I do have a history of low hcg levels in my pregnancy 5 years ago.... Didn't show positive on urine until 5 months!
