Have been trying to conceive for almost a year now have been using GO MULTIVITAMIN FOR WOMAN AND FOLIC ACID too but no positive result yet?

Unable to conceive. Male partner needs to have a semen analysis first. If normal then you should consider seeing a gynecologist.
Sexual testing. Infertility can be the issue, defined by no conception after 1 year of trying to conceive. I suggest consultation with a fertility clinic.
