Postpartum question

So my question is how long after delivery is it before your hormones go back to normal? It's been almost 5 weeks and we had a little mishap with the condom breaking 2 weeks ago and I am just trying to figure out if my test would be positive from previous hormones or new pregnancy. We weren't ttc again yet as we are healing from the loss of our twin boys who were born at 17 weeks. This is a serious question so I really don't care to hear about us having sex already because my Dr. already knows that we have had sex already.
