Question!!!

Ok so I just went to a GNC store to look for a supplement call PREMAMA for fertily and also found FERTILITY BLEND the difference it's that the premama it's 15$ and the fertility BLEND its 39.99$ the girl suggests it the fertility blend because it worth your money and it has a lot of good things to get pregnant so my question is any ladies that actually try one of those supplement and got pregnant me and my hubby are ttc#1 for 1 year and 9 months now.. what u ladies think???
