You : You should probably have an ultrasound. Pelvic exam, especiall early on in pregnancy, is not very good at determining a pregnancy. Since it has been 2 months, you probably have more information now. It is possible to have a positive blood test and negative urine pregnancy test, this is very rare if the number in the blood test is above 50.

Hpt pos: If you had a positive and then negative HPT this is likely a "chemical pregnancy" . A pelvic exam alone, without ultrasound, cannot diagnose an intrauterine pregnancy. A transvaginal ultrasound documenting an intrauterine pregnancy in the first trimester is the "gold standard" for pregnancy confirmation.
