Help!!! Brown discharge and I'm terrified!!!😞💔

I'm turning 7 weeks tomorrow and I just went to use the bathroom to pee and when I wiped there was brown discharge. Some a bit darker but not heavy/ a lot. My heart is beating so fast! I'm not in pain or cramping or spotting. Just that discharge I had just now. I'm so scared it may lead to something!!! Just because I have had 3 miscarriages at 5 weeks. My husband had just texted me earlier so happy saying he thinks this baby will stay with us now I'm so afraid!😞😞😔
