TTC/using Preseed baby number 1 help!!

my husband and i have been trying to conceive since dec/Jan.. so almost a year. got off BC last december And periods have been regular and i do believe i am ovulating. been using clearblue advanced. trying not to stress n just let it be and have fun, but sometimes easier said than done. been seeing some posts about Preseed.. what is everyone's thoughts?? my doctor said if not preggo by dec (which would be full year) then come in for full workup for each of us and go from there. I am 30 and my husband is 36. were both healthy overall. we work a lot and have crazy stressful jobs, so trying to just relax.
