I'm spotting brown ....its scaring me to death but Google said its common ...

I'm internally stressing about this...my 3 teens and pregnancies were traumatic to say the least. Apparently the pregnancy feeling is a trigger to ptsd also. I'm going to my confirmation appt. Tomorrow. Gotta work today and stay focused....i have 2 autistic kids....those pregnancies were insanely STRESSFUL lifetime movies level..... I'm convinced that's an added cause so I'm desperate to create some peace for this baby. ....have you had any spotting?
