Hi there , i tested faint positive 2 weeks ago a day after what i thought was a period(might not be) and have been faint still. I had very light spotting for 7 days. I went in for an hcg test on the first day of spotting and it was 18. I understand that it could be a chemical preg or an ectopic (waiting for appointment this Saturday) but could I possibly be further along than expected or could this be a viable pregnancy?
