Seriously I can't be the only one

I have noticed the past week my body odor is getting alot stronger I mean my armpits stink like a sweaty man it's that strong my partner even said to me "bloody hell you smell like you haven't washed or put spray on for weeks" which I have been I feel horrible what can I do to help get rid of the smell apart from washing and putting spray on all the time

P. S I'm 35 weeks pregnant
