Anxiety causing random bleeding?

This year has been very stressful, full of anxiety, many deaths in the family, stress at work, and a miscarriage. The last 2 months I've been "stress bleeding"is the only way I can think to describe it. We had an emergency trip out of the country because my grandma passed away and I bled the entire week we were there, more stressful days meant heavier flow. The minute we got back home it stopped. Then I got my regular period. That came and passed. Today I had a heavy, sudden flow. It's been a busy stressful day but it happened when we arrived at s party that I was nervous to attend. I do deal with social anxiety, but this is ridiculous. Has anyone ever dealt with anything like this?

I have an appointment this week but I want to be prepared with what to ask for (hormone panel? Therapy? IDK) And to top it off I have a medical trauma I'm still trying to cope with so I feel like I'm in a million pieces right now.
