4w6d Symptoms Fading

Nicole
Is it normal for symptoms to fade? I was having extreme nausea and really tender nipples and breasts and now it seems to have faded. The only thing I'm feeling is bloated, constipated, and fatigue. I've had 3 previous miscarriages and a ruptured ectopic pregnancy so I'm worried. This would be my first baby too. Any advice would be helpful!
