Getting discouraged

Been trying for 7 cycles. Tracking my BBT & LH strips (kind of inconsistently). I’ve tried mucinex and preseed. Got my hormones checked via blood work and everything was in normal range. Did at home sperm test it was OK. Not great but not in danger zone. Really starting to get worried that something is wrong. Any tips or words of encouragement ?! 😭 28 y/o
