Miscarriage

I am 5 weeks pregnant and I woke up last night to some cramps and bleeding both like I just started my period , not to heavy and cramps not too painful , I haven’t passed any big clots besides a teeny tiny one , is this a miscarriage ? I went to urgent care and they said they couldn’t do anything recommended me to the ER but I don’t want to wait there for hours if they can’t do anything either. I’m not in a lot of pain. I just need to know what to look out for if this is a miscarriage since I’ve never had one ….
