Loosing symptoms & abnormal discharge

The past few days I’ve been feeling much less nauseous and my breasts feel almost completely normal after being so sore I couldn’t stand to lay on my side or stomach. This is my first pregnancy, I’m 8w4d and I’m so scared that I might be loosing my baby. I’ve been having small jolts of dull pain in my vagina and have had some strange discharge. I had this discharge (picture reference) yesterday and today after bowel movement, and it had a little brown in it as well. Has anyone else experienced this or anything like it?
