8 weeks pregnant

Hi mummies! I'm almost 8 weeks pregnant and 2 days ago, I noticed a light brown discharge. I thought it was one time, so I brushed it off. Last night, it was slightly darker, also just that one time. Today, I noticed a spot of brown blood. So far no other fresh bleeding accompanied by cramps or anything else. The brown blood was also just a very thin streak. Should I be worried? My first appointment is in a few days. Should I let the gynae know as well? Thank you in advance mummies! Any input will be greatly appreciated. #pregnancy #firstbaby #1stimemom #advicepls #pleasehelp
