anyone bleed while pregnant

I was 31 days late on my period on the left photo labeled December 10( I didn’t mean to put 2025) the same day. I started bleeding like my period, but only for three days. It was way shorter than my period Normally is. on the third day, I went to my OBGYN to be checked for PCOS and I just self diagnosed and ruled it as a miscarriage.. when I got there, she said it may be too early and I didn’t get pregnant when I thought I did or I ovulated twice in one month because there’s no sign of a miscarriage besides the bleeding, but my pregnancy test is still positive that day .. so I’m scheduled to come back in two weeks and they drew hCG … this morning I woke up just to see if the line got darker and it did yesterday morning I had a faint positive , this morning I had a 100% positive in 60 seconds… I’m scared to celebrate because I was bleeding any advice? While I wait for my results, I can’t stop thinking about it.
