strange smell normal in pregnancy or should I be worried?

F
Hi ladies, I'm a FTM so I'm at a bit of a loss here. I'm 29 weeks tomorrow and the last week or so I've noticed when I go to the toilet I can smell something different to normal. I don't really know how to describe it, it doesn't smell particularly bad, but not particularly nice either, just different lol. I thought at first it might be my urine, but upon sniffing my underwear, where a lot of the time they are a bit damp from all the vaginal mucus and stuff, that it is my vagina. I'm not itchy or in pain or displaying any other symptoms but this. Is it something I should worry about or is it normal for your vagina to smell a little more... distinct in pregnancy? Lol.
