Sorry for TMI, but....

Okay , so I'm 16 weeks and 6 days today and currently on my holiday . I've just gone for a shower after a day by the pool and noticed that my nipples have got some white kind of dryish, but not completely dry discharge in (?) them. I don't know if this is normal , whether it's colostrum or whether it's just so cream that's gotten down there 😂😂 but it's on both nipples ??

It's my first baby so I'm unsure of all of this ! Thanks x
