Venting 3days late

Took a test 2days before missed period got a negative. 3days late as of today and haven’t gotten the strength to test again, been ttc for 1 year and 4 months know.... with my first it took us 1 year and 1 month of us physically living together actually trying before that year we would only see each other Once a week it was always unprotected yet never became pregnant why can’t we be like other couples who just get pregnant within less then 5months or first try why is this so hard...sorry just had to let it out some how
