For DS1 and DS2, DH was working overseas and for both he arrived back at 38 weeks. I had a doula for both births as our parents live overseas. Having a doula definitely put my mind at ease that in the event I went earlier than 38 weeks I did have support for the birth itself. Having said all that, and I know that it is a different situation to yours, with DS1 I was 7 days over and DS2 I was 10 days over, so even though I was panicking that DH wasn't getting back till 38 weeks, we will ended up waiting around for 3+ weeks for both bubs to be born. Is there an option of you having a doula for extra peace of mind. I think I would keep DH to his roster and have support that you are comfortable with in the event that you did go early. It is tricky, I know getting close to both births from about 36 weeks onwards each night I would go to bed and cross my fingers and say 'please don't let anything happen tonight' lol and then when DH got back I felt a huge sense of relief. No matter it will all work out hun, but it is stressful I know, good luck with it. x
