Hi there I have two kids. I have had a vaginal delivery and a c-section so, you could say I am experienced.
For constipation: it doesn't taste very good but prune juice is the way to go.
For urinary tract health: cranberry juice. Plus it will take the sting out of your pee if you have an episiotimy or tearing.
For yeast infections: everyone seems to forget yogurt will kill a yeast infection within 24 to 48 hours.
Walking: don't run, walk. Every single day. The more you walk during your pregnancy the shorter your labor will be.
Eating: you are not eating for two, you are eating like a woman who needs to get all of her daily nutrients. Three square meals a day and two snacks.
Sex: have a lot of sex. It won't hurt the baby and after the baby comes you will never see it the same way again.
Take your prenatal vitamins (before you concieve) and do not miss a single doctors appointment.
Last, print this out and take it to your doctor so he/she can tell you why I am right.
