Progestin question

So, i am panicking at least for the next few days.

I had sex about 10-14 days ago, and I had some bleeding happen that seemed like textbook implantation bleeding according to Google. It terrified me.

First of all, I'm trans so any bleeding is scary and triggering. Secondly though, I am currently on 2 forms of birth control and Google doesn't have any info that I can find!!!

Basically, i had an IUD (liletta, hormonal) since 2019, and got it changed about a month ago. Due to complications with reinsertion, they gave me a depo shot to help keep away my period in between getting my IUD removed and re inserted. I had my IUD reinsert 2 weeks later, meaning I was on depo AND IUD during said (admittedly not protected) sexual encounter. That encounter was last wednesday?? Like over a week ago wednesday, with it being Tuesday night now. So 13 days ago. I have had light spotting since Sunday, it went away today. It came with cramping, it was brownish in color. Not as bad as a period, cramping was light but noticeable given the lack of cramping in recent years.

To reiterate: depo about 6 weeks ago, hormonal IUD about 4 weeks ago.

Basically, given that I didn't have ANY bleeding, no spotting, no cramping, etc. For however many years, this little spotting and bleeding is scary to me. The IUD was replaced a month ago so it can't be directly tied to that right? I had spotting day of but that was it. Could the double dose of progestin cause pregnancy symptoms? I'm gonna test again this weekend!!! Im hoping that it is probably normal to bleed a little and cramping a little if on 2 forms of birth control???

Ive also been extremely emotional, like cry at every little thing emotional, had cramping (which is also something I never experienced in the last however many years with my iud) and gotten really bad carpal tunnel flare up and congestion. I'm gonna test again when I can, specifically a week after suspected implantation bleeding, but the chances that I am pregnant are negligent right? This is probably just my body being weird? I also don't have breast's or nipples, so when I Google symptoms and it says breast sensitivity, I have no ability to Guage that.

If i am..... ugh. I know it will likely be ectopic and nonviable, and I have safety and support in that area. I'm very pro choice. But I would never make that choice willingly. And I don't know how I'm gonna have to handle that. I'm terrified. If i get pregnant, I would always choose to keep it. So it breaks my heart thinking that if i am against all odds, i might not be able to.

If it WAS implantation bleeding, Google said I can test as early as Thursday. It is hard for me to access tests currently, so I have one waiting and im probably going to wait until Sunday or Monday. But I guess I am looking for reassurance or similar experience in the meantime??

Absolute panic happening this new year!!! I don't normally post on reddit about personal shit but I'm panicking so much because I cannot find any info online. What if an IUD isn't as successful when paired with a depo shot? What if my body is just betraying me due to too many hormones? Am I just crazy??? Ive been crying nonstop all week and having weird pregnancy dreams so I just have a bad gut feeling. But i know I have to wait to get a clear, definitive answer. Please help.

Thanks.

Tldr: depo and IUD, sex, afraid I might be pregnant
