Are pregnancy symptoms in any specific order?

No specific order as each woman's body will react to the symptoms as they come. I know some women who never had morning sickness - I was one of them. It is a general list of symptoms that occur when they do. It sounds vague, yes, but you cannot pinpoint the order for all women. Yes, there is breast tenderness, cramping, nausea, morning sickness, loss of menstrual cycle (but there are women who swear they still have their periods while in the third month), there can be moodiness, crying spells, fatigue, and ankles swelling. But there does not appear to be an exact order of symptoms.
