Smelly urine no burning/pain when peeing but vagina itches & hurts to wipe w/toilet paper like its cutting me down there im 13 weeks preg what's wrong?

Discuss with OB. Could be a urinary tract infection, yeast infection or bacterial vaginal infection. Yeast infection is probably highest on the list. I'd discuss it with your OB.
Be checked out ... Be checked out if you have UTI, BV, or others by gyn-doc or dedicated PCP ASAP, especially while in pregnancy. Meanwhile, bring the info on the onset, degree, duration, and progress of all related symptoms over time to Doc for analysis, physicals, and tests as needed so to deduce possible Dx for reasonable Rx / care. Best wish ...
