anyone having earlier symptoms with baby no 2?

Jac • TTC#1 rainbow after recurrent MC. 37years old. Very low AMH level.
I have just found out I am pregnant (I am 5 1/2 weeks) and I already have a 7 month daughter. This time around I have really strong symptoms - nausea, exhaustion nose bleeds, bloating since 3 1/2 weeks. I didn't get these until at least 7 weeks last time. Anyone else experiencing this with their 2nd?
