Can anyone give some insight?

So I have PCOS. I found out I was pregnant October 23rd and Dr said I was very early (hcg of 28). I thought I'd never get pregnant so this was such a big surprise even though hubby and I were trying very hard! My hcg more than doubled my next appointment (128) so all was good. Then November 7th I began to bleed and hcg had dropped (112). I lost my little baby. I was around 4-5 weeks. I seemed to pass everything Nov 18th and stopped bleeding around Nov 22nd. So my hcg never got very high. We got the all clear to start trying again immediately.

So here it is, December 8th and I'm still getting positive pregnancy tests but they are getting much lighter so that's good! 🔆A couple days ago I started getting brown spotting and a couple very light cramps, the next day was the same but at the end of the day I wiped and there was bright red blood all over the toilet paper. I figured it was AF and put in a tampon. Changed it before bed and there was just a little bit of blood on it. Put in a new one, went to bed. Woke up and the tampon was dry as a bone! The bleeding had completely stopped. Only one wipe of red blood, is that weird?? Was it a period or something else? Could it have been a heavy IB? Has anyone experienced bleeding like this?🔆 My IB with the baby I just lost was light brown spotting with a little bit of red a couple times and lasted 4 days. If anyone has any thoughts of why I bled like that then please let me know. I'm so confused by my body right now and just want my rainbow baby so bad! 🌈
