8w2d - Bleeding scare

I'm so scared. Yesterday I flew interstate for work, & I went to the toilet just before my busiest time. I wiped & there was brown discharge. It continued on & off through the evening & this morning. Today there was a dark brown stringy clot (sorry for TMI). It's the weekend. I have a check-up scheduled already with my GP tomorrow after an early work shift. Google is scaring me. Some positive outcomes but a lot of bad ones. I don't know how I'm going to sleep tonight. This can't be happening. Please please please let my baby be ok. I've seen his heart beating. He's real. I can't let him go now!
