4 wks pregnant after previous miscarriage

I'm so anxious, I have some pretty strong positives on a few different pregnancy tests. I am day 28 today and yesterday evening I had some light pink discharge. Today I have the same but not as dark. I had a miscarriage at 5 weeks last year so I'm so anxious. Do you think these tests show that everything is ok and that the spotting is normal? I am trying to reassure myself that what will be will be but I'm scared 😞
