TTC 3 YEARS

I'm 24 and my fiancé is 25...we have been ttc for 3 years now... September will be 4. We haven't seen a specialist.. I guess we are just afraid to hear bad news.. I talked to my doctor once... Back when we hit our one year mark.. He didn't seem worried. My periods are 32-40 so, they aren't normal but to me, they are. I've tried ovulation tests... I took one every single day for a month and never had a positive sign.. We've had sex every other day, every 2 days... Every day! Nothing seems to work.. We've tried an at home test for him to be tested... His count was Low.. Or so it said.. And then we tried these Fertility blend vitamins for him for 3 months... I've also tried clomid and yet.. Nothing! I feel really frustrated and scared..and most of all really sad..... I'm just looking to vent I suppose.. =(
