7 weeks strange pain

So last night I had one big blob of deep dark reddish brown discharge no clots not a egg white texture, it was just like thick cm. Then it went away to light brown. Then when I was laying in bed a few hours later, I started feeling a weird stomach tightness & back pain similar to when I had my miscarriage before but it only lasted like 5 to 8 minutes and never came back. So when I woke up there was nothing in my underwear but when I went to wipe there was some pinkish brown discharge with what looks like white flesh inside. I can’t call my doctor because they will not offer any advice since I am a new patient and have not been seen yet. Only thing they’ve recommended is for me to go to the hospital but I don’t want to go for nothing. Has anyone else experienced this ? If so what did it turn out to be?? I’m nervous I assumed this would be a healthy pregnancy with all the morning sickness I’ve had this past week.
