Crazy stress! Help!

So I recently found out I'm pregnant due in February, my first appt. Is June 29th. My husband and I planned on telling parents after our first appt. Since life has blown up. My parents are going through a tough time and are possibly divorcing. It's totally come out of left field, because of some recently discovered things that arose. Now I have no idea when the best time is to tell them?!??! I don't wanna add more stress to an already stressful situation.
