I got these ones from Walmart for about 5 bucks my doc said they are perfect I showed them to her...they are spring valley prenatals multivitamin/multimineral in a green & yellow bottle ...100 tablets come in a bottle
You can take Flintstones vitamins, they act the same as prenatal vitamins
You can get just a regular prenatal vitamin OTC, make sure it has folic acid as that's the most important right now, and you'll be fine until you visit your doctor he/she will prescribe you something after your first visit. Congratulations!! :)
