Really worried

Abby • Expecting my first after a long journey of ttc
Hello. I'm 9 weeks pregnant and last night I had some fairly strong cramps. When I woke up this morning when I wiped there was brown discharge. And some more the next 2/3 times. I phoned gp who said hospital can't help because it's the weekend and have to wait till Tuesday. Going out of my mind with worry. Anyone have any experience of this? It seems to have stopped right now  Xx
