Am I pregnant again

I lost my little angel at 71/2 weeks on 30th November. I bleed for 6 days and miscarried everything naturally. I had a scan on the 2nd December to be told everything had gone and my body had gone back to normal quickly and if I wanted to try we could. Me and my partner have been having unprotected sex. I haven’t had my period but have had a few positive tests some fainter than others. I got a positive digital and a negative digital? Could I possibly be pregnant again? Very early?

These tests are all from the 21st December - 30th December.
