Getting Discouraged: Vent Session

Me and my partner have been TTC for about 4 years, we haven’t used OPKs the entire time but we have on and off and just recently started using them again, this is our second cycle using them this time around and we've been doing everything you're "supposed" to do to raise your chances of conceiving(ie. Finding my peak, baby dancing every other day of the fertile window etc), AF is due tomorrow so I took a test this morning and it was stark white. I'm just feeling really discouraged, I know its only our second cycle tracking everything again but the fact that we've been having unprotected sex for multiple years and still haven’t become pregnant worries me. I've been considering making a doctor's appointment and asking about fertility help but im afraid they'll just tell me to keep trying without offering any options and I'll basically wind up going in for nothing. I just wanted to get this off my chest, thank you to anyone who took time out of their day to read this <3
