I would go to the er and get checked out bleeding is never anything to mess with plus you've had clots at 5 weeks they should be able to see the sac they might not see anything else but they could eliminate if you miscarried or not sadly there is nothing that can be done to stop a miscarriage but you can bed rest pelvic rest and drink plenty of fluids good luck mama
If you're that scared, I'd go to the ER. Especially because you say you saw blood clots and something else. I would imagine they would be able to see something with an ultrasound. After the experience I had with my eldest son's pediatrician 13 years ago, I no longer just sit and wait.
Unfortunately, there isnt much you can do but wait for results I guess, rest up! all the best
