I take CVS brand multivitamins with an added Folic Acid supplement (since some MVs don't have the needed amount). They are not chewy, though.
Just a head's up - most people feel nauseated because of the Iron in vitamins. I believe (although could be mistaken) that Vitafusion chewables have no Iron. If you take one with Iron, try taking it after eating - a bit of food in the stomach appears to help.
I agree with Cole - your family's fertility has no baring on yours. It can take a perfectly healthy couple up to a year to conceive a baby. Welcome and good luck. Read the newbie link if you have not already - there is some great information in there.
