Stressing over money/maternity leave!

I'm 30 weeks today and feeling super emotional lately. On top of it, I am starting to really stress out over money. I'm a teacher, so my last two pay checks are coming up and I'm due in mid-August. I will only earn one paycheck in Sept. and the payout from Aflac (which only covers a portion of my monthly salary). I may get some money from the state, but I can't really bank on that money or predict when it will come. Also, on top of all this, my district wants me to pay $1300 towards my health benefits now, rather than waiting until I return to work. I am starting to feel like my husband and I will never be able to do this!! He makes good money, but we have a lot of bills that add up. We have been saving but I really don't feel like we have saved enough. Starting to stress out and I feel like I can't even enjoy my maternity leave because we will be struggling. 😭😫 Sorry for venting I'm just really overwhelmed.
