husband gone on deployment

I am about 18 weeks now and my husband just left to go on deployment. I am sad as well as scared. I'm sad because he will miss a lot, my birthday, baby appointments ect. I'm scared because I will be alone for all of this. I am scared because we won't have any communication for the months that he is gone. I am scared because I am self conscious now and he will be surrounded by women (not saying he would do anything but the hormones make me crazy I never get upset at him for this he is just doing his job). I am scared because I have to clean our cat litter and mow our grass now lol. basically I'm trying not to stress because I know it will be okay and that it is temporary but I am going to miss him and wish he were here. Does anyone have any encouragement or has anyone expiereneced this before? we've been apart before but not while I was pregnant. thank you in advance for your support.
