8 weeks pregnant and spotting after severe emotional distress

Jennifer
Hello all... I'm feeling really alone right now because my husband as I have been having a tough time lately. I'm about 8 weeks along and have had a scan already which showed the baby was fine and good heartbeat but they were off by 3 or 4 days of what I thought I was and said 7 weeks and a few days. However last night I had an argument with my husband and his close friends all essentially ganged up on me to make me feel bad about something stupid. I allowed my emotions to get the best of me and I basically broke down sobbing and was hysterically hyperventilating at my sister's house an hour after the argument. Within 5 to 10 mins of me breaking down I felt something come out and it was a light brown or dark yellow color. My sister said it looked more dark yellow to her. However this morning when I wiped there was definitely light brown on the tissue. I feel a little crampy and uncomfortable but nothing severe. A lot of pressure and some ligament pain. I'm just wondering if extreme emotional distress like that can cause a miscarriage to begin... I called my obgyn office and they still haven't returned my call. I'm wondering if I should drive myself to the hospital but I have a 4 year old as well I'd have to take with me. Has this happened to anyone else after getting extremely emotionally upset? I don't know what else could be the cause of this and I am so scared. I feel like I have no one to reassure me. I tried to tell my husband and he just walked away saying I did this to myself. Please help me...
