STI or Pregnant? Cant see Dr for a week

I justtttt had my period (9/17-9/20) The flow was normal for me (moderately heavy) but I usually go for 5 days rather than 4. I also had worse than usual cramps, and the cramps lasted the whole period when usually they stop after my heavy day 2. On 9/21 and 9/22 I had the normal dark maroon dried blood that I always have. By the end of the day on 9/22 and allll day 9/23 (and currently as I write this) I’m having thick (not super thick) discharge with blood. And it’s definitely fresh, red/pink blood not the dry post-period blood. Bloody discharge. I have never had this kind of discharge in. my. life. I’ve had yeast infections, BV once, and even chlamydia/trichomoniasis (I put them together because i caught them both at the same time from the same person 🤦‍♀️) when I was 17. Just giving that history because at this point (25 y/o) I KNOW my vagina, I know when something is off and I 9/10 I know what is wrong. But I have never before, not even with the STD, had bloody discharge. There is no itching, no burning, and no weird smell at all. My vagina feels and smells completely normal, but every couple hours I go to the bathroom and theres thick bloody discharge. I also have very mild cramps, so mild its hard to tell of they’re cramps or gas sometimes.

I would assume this was implantation bleeding and cramping if I hadn’t JUST come off my period. RN my mind is jumping to a dormant std that’s turned into PID. I can’t get to a Dr. right away that is why I’m posting here, pleaseeee help!
