Premama

So I'm on my second day of take premama concieve and I have regular periods and I ovulate on my own so I had to wait for af to come so I could take it. Has anyone else taken premama before and gotten the bfp? I have heard so many positive reviews so I thought why not. I was also wondering if it mattered that I didnt take the premama prenatal vitamins since I bought some prenatal vitamins at walmart which are more affordable. Is it best to take the premama vitamins or does it matter? My fiance and I have ttc for baby #1 for 4 months...so we thought why not try this.
