Pregnancy confusion

I’m so confused about me not being pregnant but having a few positive pregnancy tests.

On July 30th I took 3 home pregnancy tests and they all came out positive. I also was spotting pinkish blood but not heavy enough to go on a pad and lasted a few hours.

So on August 6th & 8th I went to my doctor and gotten a pregnancy test both times came out positive also and my doctor scheduled me for a sonogram. Also on the 8th I started to spot again this time it was brown blood but not enough to go on a pad nor I had any tummy pains and it ended on the 12th

On August 20th I had my son grams I would of been 8 weeks and they don’t see no sac or baby.

So I did a blood test on August 24 and got the results back on the 27th to find out my levels are 0.

So do you guys think it was my period or did I miscarry?

I was suppose to start my period on July 30th but it never came. I put on glow that it was a period and af was due yesterday but still hasn’t came. Should I just wait it out this whole month to see what happens or what?
