Am I in the clear?

With my first 2 pregnancies I had real bad postpartum depression.

With my 1st I was too ashamed to seek help and self helped myself

With my 2nd I got help and was medicated for it

But as I’m 3 weeks postpartum with baby #3 I feel surprisingly happy and at peace and basically I feel like myself (I do feel a bit sad due to me having my tubes tied but not to the point of crying, more like it’s the end of an era lol, bittersweet)

Am I in the clear for not having depression this time or is going to creep up on me?
