Kinda personal but dk where else to ask.

I'm almost ten weeks. I live in VA and it just started getting hot enough to wear short sleeves and be outside for most of the day. Over the weekend, I noticed my armpits have more of a BO scent to them than they normally do. I use clinical strength deodorant already. Is this due to hormonal changes, or is my nose just more sensitive than usual? Also, has anyone else experienced this, and how do I tame the smell?
