How do I know if I'm having a ectopic pregnancy???

Z

I'm going through a miscarriage. I'm bleeding as if I'm having a period. My fear is a ectopic miscarriage. Just wondering what I look for. How do I know if I have it. My ob has not given me any info on what to do during all this. I'm so lost and scared. They said they will call me tomorrow for my levels. I know they have declined since I'm bleeding heavy with clots. The lack of information has me worried 😞. Please anyone can help me in this situation
