I have took a urine sample into my doctors after I got two lines on my pregnancy test and a positive on a digital. I have rang back and it says inconclusive! And I have to do another one😨 what does this mean! I'm concerned and they receptionist didn't say much! When I did my test they was two lines.. yesterday! I'm two days past my period. Please help!

Iv had a previous miscarriage and now I am very worried!😭
