8 weeks pregnant & bleeding

Hi, so this is the first time I’ve posted on here. I’m 8 weeks pregnant and for the last two days I’ve been bleeding, enough to have to wear a pad. I went to a&e; the other night and they weren’t concerned as it wasn’t soaking the pad every hour or so but I have an emergency scan this afternoon and I’m absolutely bricking it. Has anyone else been through this? Sorry if it’s too much information, I’m just starting to feel nervous and worried now. There’s the odd pain in my side but nothing severe, feels more like a stitch that comes and goes. Any advice would be truly appreciated x
