Hi ladies, I am in 6 w 5 days, I have been taken Wellwomen fertility tablets since April. There is 400mg folic acids in each tablet. I still have one box need to finish. Can I carry one to have this one or I have to buy folic acid own tablets. I checked ingredients for Wellwomen pregnancy tablet, compared with fertility tablets, the only different contains vitamin K in pregnancy one. Is VK very important?
