How soon can I test after miscarriage?

Hi ladies! I miscarried 9/29 finished bleeding about 10/2. I had my last ultrasound 10/1 to make sure everything was gone. My Dr told me my period could come within 4-6 weeks from 10/1. We started having sex immediately the next week after the bleeding stopped & according to my last ovulation I would be ovulating from 10/4-10/10. My doctor told me to test 10/13 and it was negative. My period (according to last one) should have been from 10/23-10/27 but I still have not had any bleeding. I experienced some cramping last week and the same symptoms that I had last time I was pregnant and Im wondering how soon I should test again? Has anyone been here before? All comments are welcome 🙏🏽 🌈🦋 ps i was planning on testing 11/03 but i want to test today 🥺🥺🥺
