Trying Not To Panic (TMI)

Last night, around 10p, I went to the restroom and there was blood when I wiped. Earlier in the day there was a little bit of brown discharge but not enough to make me worry. The blood I was wiping last night was bright red and I guess it was more like spotting? It was only when I wiped, none on my undergarments and it only lasted about 5 minutes before it started getting really light brown/pink. By this point I'm tearing up because I'm nervous as heck that I'm going to lose my baby and my husbands trying to calm me. I finally get up out of the bathroom and am wearing a pantiliner. We agreed to call my doctor this morning (who is not answering!!!!!! 😡😡😡) and not to panic. The pantiliner was clean this morning which means the bleeding must have stopped but my stomach still hurts a bit. I guess it feels nauseous but I haven't had any morning sickness so far. I'm 6w4d today and not sure what to feel/think/do. I'm at work and trying to avoid going to the hospital if I don't have to. The question is, do I have to? I'm asking you guys since my doctor isn't answering.
