I'm 2 weeks late getting signs of pregnancy but 3 tests say no. what's going on

Hi, my period not come for 2 weeks.. So I took pregnant test.. It is negative. Have to wait 2 weeks more later.. I took pregnant test again... it is positive. But I lost the baby:( so important wait to see 2 weeks more later.. . Could negative is fake if still then see your doctor.

It is possible, that your hiornmones are slow to build up high enough to show positive on a urine test. Your homones need to be a certain height to show positive on a urine test. If your hormones fall a fraction below the required level, you will get a false negative result. If I were you I would ask the doctor to take a pregnancy blood test. That will show any rise in your hormone level, to indicate pregnancy or not. Good luck.
