Pee smelling strong and different

Rimmy
Hello Ladies , 
It am in need of some advice ... sorry for TMI , I am on my 17th week of pregnancy and I don't remember since when but my urine smells bit weird little strong not too but I do feel some lingering smell in my underwear apart from that I drink lot of water, and my pee is usually very light yellow to transparent , there is no itch or anything whatsoever ... is it normal during pregnancy ? Or should I be concerned and contact my OBGYN ? 
Thank you 😊
