Husband work trips

Hi, I would like to get some advice here. My husband have been traveling and he has an upcoming trip (close to 2 weeks) to be away. We have been quarreling on this point and it’s affecting our relationship as I feel unsupported in my pregnancy. It’s tough balancing being a supportive wife as it’s a legit biz trip vs meeting my own needs as I am a more anxious first time mum. Currently in trimester 2z Any advice would be appreciated!
