Possible tumor: There are several things that can cause an elevation in hcg, the most common test used to document pregnancy. However, this is also elevated in some tumors. I am sure your ob/gyn will be obtaining additional studies and do addition imaging evaluation to find out why. ...Read more

Hmm, well...: The negative test and fact that your period is now present would go against being pregnant. It does sound as if you were pregnant though in the recent past. Miscarriages are more common than you would think, and maybe your body was not ready for pregnancy. Not definitively sure though, ..you need to see the GYN Doctor as you need an exam to treat you either way. Best wishes, God Bless ...Read more

Possible follow-up: Qualitative pregnancy tests of either urine or serum may screen for different "cutoff values" for hcg; therefore, early in pregnancy some qualitative tests may be positive and others may be negative depending on the manufacturers cutoff for a "positive" level. With time all qualitative tests become positive as the levels of HCG rise. Repeat the urine test in a few days to a week to know for sure. ...Read more

Here are some…: I'm glad to see you have received such wonderful medical care; however, based on currently available information, it would be most logical to direct your current concern & question to the treating doctor for confirmation & counseling so to minimize potential confusion and anxiety, which commonly results from online inquiry. Of course, make sure to supply detailed Hx stressing sequence of events. ...Read more

Confusing!: I agree that's pretty confusing. Since your period started it makes pregnancy much less likely: I recommend getting a quantitative hCG with a doctor as soon as possible to resolve this. Good wishes. ...Read more
