False positives are possible. You could be starting AF. Maybe you should wait a few more days and try testing again with a different test or a follow up with your doctor.
i agree... false positives are possible.... give it a week or so and if you still have no period then go for another test...it may be to early to tell anything right now
sometimes the ultraound wont show up anything. i had one done so early that he hadnt implanted yet i just had that high of hcg that the test was positive. waited 2 weeks did another ultraound n there he was :) so every preganncy is different
and then the bleeding started. I went to the ER, they basically were rude and sent me home. I had an appt. with my regular OB/GYN and they confirmed I had had a chemical pregnancy this cycle. I also had positive tests then negative. The only way to be sure is to take a blood test. Good Luck to you.
