For current pregnant ladies and moms: When Do Symptoms Begin?!

Megan
I am currently 4w5d with my second pregnancy. My first ended at 10 weeks with a missed miscarriage. Currently my only symptoms are bloating, gas, sore breasts, tiredness, and mood swings. Will there be anymore symptoms that will appear and if so, when do those symptoms begin to develop?!
I am very nervous about having another miscarriage and I need a piece of mind from more experienced ladies.
