You probably have a UTI. They are very common in pregnancy. You need to tell you OBGYN. Don't let this go.
I would call the dr in the am it sounds like a UTI
Your urine quality should be mostly unaffected by pregnancy. Sometimes it will get darker, sometimes it will get lighter, sometimes smell more..sometimes smell less...but a pink tint could indicate a problem with your kidneys or a Urinary Tract Infection (which are incredibly common during pregnancy due to the baby's weight pushing on your UT system and slowing everything down), even if you don't feel symptoms. Just to be safe, because infections can affect the baby very quickly, call your doctor first thing in the morning and ask what they recommend you do.
Good luck! Congrats on making it to full-term :-). You could meet your little one at any point :-).
