Odd question..

Okay so quick recap: this is my second pregnancy, (didn't experience this w/ my first, nor ever in life so far,) but since I've became pregnant I've embarrassedly been informed of something.. My hubby woke me up this morning while laying his head on my chest right by my underarm & was  like "oh babe! BO!" Twice now! I've never had this problem.. It's like so strong it's through my shirt.. Has any other women experienced stronger BO while pregnant??? This is just crazy to me.. My deodorant has always done the trick & I've never really even had strong BO anyways.. Talk about embarrassing.. /:
