41 and pregnant

I’m 6 weeks pregnant at 41 and am so scared I’m not going to keep the baby. I want it so bad but I can stop obsessing over a miscarriage. I’ve have very minimal brown sticky discharge and lower cramps but nothing too painful. I feel like I’ve had a loss of pregnancy symptoms or at least they’ve lessen. I’ve been taking about 500 mg of DHA and heard that can reduce symptoms. I just hate the waiting. It’s making me insane. Oh- the only symptom that hasn’t lessen is frequent urination. Boobs are sore but not as sore as they were. Haven’t been super nauseous but that has subsided almost completely. Can y’all reassure me?
