6 weeks pregnant and spotting

About 1 am Friday morning I woke up with some red blood in my underwear, that day I had brown spotting only visible when I wiped. The next morning I woke up to nothing then within 20 minutes of getting up I had a small amount of blood. Then it went to brown discharge and by afternoon almost nothing. Woke up this morning dark brown blood type discharge still only when I wipe none on the pad. So far just brown discharge today. I’m out of town on a business trip and haven’t even seen my obgyn yet because I just turned 6 weeks yesterday. I’m so worried I had a missed miscarriage in 2018. I’m afraid I’m losing the baby.
