I'm 7 weeks pregnant and have a little bleeding but no abdominal pain. Is it okay?

Hello doctor, I had an ultrasound and the doctor diagnosed me as 5 weeks pregnant (empty sac in the uterus). Now I have heavy bleeding with 2 large blood clots (naturally). After a check-up, the doctor said I could no longer see the gestational sac in the uterus.

Currently, I am 4 weeks pregnant and still have a cyst on the left ovary. I had brown bleeding for 2 days and then I went for an ultrasound but the doctor said nothing. On the 3rd day, I still had brown bleeding, a few drops all day, half of the daily sanitary napkin. So doctor, can you tell me if brown bleeding at 4 weeks pregnant is okay? What should I do, doctor? Thank you.
