Scent of pregnancy?


I am on my fifth pregnancy, and both last time and this time, my husband told me I was pregnant even before I missed my period. He says he can tell because I smell different, that my base scent has shifted and it’s not anything like using a new soap or perfume. What gets me is that both times he was right AND he knew before I did. The first three pregnancies we were active military and saw each other as ships passing in the night, didn’t really have a chance to sorta revel in it and have all the discussions like this. Is it silly? Anyone else ever noticed a change in your scent/body odor due to hormonal changes like this?
