I'm going to make an appointment with my GP and will post an update.
I thought it was just me over thinking ,but now that ive looked on this website and read others describing the same increased odour in the same places as me, i feel reassured to get it checked out.
This is an example of one of the helpful threads I found..

I'm not sure if it's because I've put weight on slightly but I've noticed my body odour is alot stronger around my arms and boobs which is making me paranoid. I also think my vagina smell has changed, not fishy or anything but more musky. Did anyone else notice this?)
