It could also mean its too early to see anything on an ultrasound. I would follow up with a doctor in a few weeks.
it might also be an ectopic...i had that in the summer. All the test were positive but when I had an ultrasound she said "are you sure you're pregnant"?
that was a bummer...
hope everything turns out ok.
it could mean that your HCG levels are not high enough to result in a positive urine test or that you had a miscarriage. they want to you wait to go to the OBGYN because your levels should increase by 60% every 48 hrs so they can order more tests.
I know I had 5 positive HPT tests but the day I went to the dr to confirm ti the urine test there was negative. within about 15 mins of my appointment, the miscarriage started. A week later, I was sent to emerge and they referred me to an OBGYN or atleast they were supposed to because they thought I needed a D&C. but the referral was lost and ended up causing a lot of issues for me. Hopefully you don't have that happen to you, its not the most fun thing to go through.
