Has anyone dealt with this? I started my last period 6 weeks ago. On Monday, I had a positive urine test. On Wednesday, I had bloodwork done. I got the results back today (Friday), and the results were negative. I've had a number of pregnancy symptoms and no symptoms of a chemical pregnancy or miscarriage. Could this mean twins? Why would I get a positive urine test and then a negative blood test just two days later? (The urine test was absolutely positive.) By the way, I am TTC.
