Positive serum test but negative urine test. Please help me.

Anak, this is really something you need to discuss with your OB right away, hindi ito normal situation, and your doctor needs to see your actual test results at blood work to figure out what's happening. I know it's scary, especially first time, but please don't wait, get an appointment soon or go to your clinic so they can do a proper check-up, okay? Your doctor will explain what the thick endometrium means and why your tests are showing differently. Rooting for you!
