Blood test at 9 weeks less than 0.6 hcg, negative hpt, two positive ovulation tests. Am I pregnant?

Pregnancy Test. You are not pregnant. Just because you ovulated does not mean you are pregnant.
No. You may have a cyst that is making a hormone that is causing a false positive ovulation test. See a doctor. Stress can have the same effect.
Back to school? There is a mental health condition common in medicine where a female ignores all rational evidence of not being pregnant. You are so obviously not pregnant perhaps it is time to see your therapist? Or to discuss your obsession despite this evidence with your family doctor?
