Re: Smell
Odor in urine, burning sensation, and frequent urination are all symptoms of a Urinary Tract Infection (UTI) as well. Take a break from the iron pills and load up on water for 24-48 hours. If you feel no relief, then it's a UTI and you need to see a doctor for an antibiotic prescription as you don't want it to spread or become severe.
About iron tablets....I take them myself. And they're pretty strong supplements and not easy to take. It's best to take an iron supplement with a meal. And it's recommended to take it juice or vitamin C because that helps your body absorb iron better.
