you did urine HCG
test yourself. Why dont you do confirmatory test in Laboratory? im not sure about your HCG diet for weight loss
. Some where it is said that current HCg drops intake make false pregnancy
test positive. but you said it is 6week ago.
Please do confirmatory test in lab so that you can be confirm. THere is low chance of false HCG +ve as u had taken 6week ago but also for your confirmation
