my big fat positive

I had a miscarriage(1st child) back in March and I bn trying to get pregnant since. I read online that Geritol help people get pregnant so I started taking it this month on the first day of my period. My period is due on Wednesday 5/31 but I got my big fat positive today Monday 5/29. I started testing on 5/25 I saw the very light line but I didnt really believe it today i tried a bunch of different brand so now I'm 95% sure that I'm. I just hope and I'm praying I don't have another miscarriage. So now I'm supper excited but terrify the same thing might happen again.
