Sort of losing my mind

Jessica
Okay, my husband and I have been trying since May-June of 2014 with no success yet. I'm following/doing everything I can. The only thing I'm lacking is working out a little more probably. We are also trying PreSeed and using that when I'm ovulating. 
My 'most fertile' days are happening right now - actually today is my peak. So, we've been trying every other night as I've read that it helps the male role's sperm count increase. 
Any other suggestions? When should I test after my ovulation is finished - before my next period? I'm just lost and any guidance will be appreciated. I'm so close to giving up I feel like.
