A few questions about a Do it your self divorce in Pennsylvania!?

Ok as to the parties involved, neither can afford an attorney of any sort. They are filing a divorce with a do it yourself divorce packet. They have been living and apart for more then two years. They are both agreeing with the whole divorce. They have nothing to fight over, and have one child, but child support was already established, and they are in agreement with a custody agreement. Now as to my questions. The plaintiff is the wife. She is pregnant. In the state of Pennsylvania can you get a divorce while being pregnant? It is not her husbands, as I stated they have been apart for more then 2 years. Now, the Defendant is in the Military. I seen in the divorce paper's that there was a form that needed filled out stating the Defendant was not in the Military. What is the Plaintiff supposed to do because of this. He is not deployed yet. They are trying to get this done before he is deployed again in 4 short months .Without an attorney will a judge still grant the divorce without the Non-Military form being signed? Now my last and most important question. What forms need to be notarized? Some of them are marked, but others aren't. Now it seems weird to me that a plaintiff can just send a defendant forms to sign, without being notarized. Who is to say the plaintiff didn't sign them herself? Sorry it is so long, but thanks for any and all help I can get on this!
