try prenatals before hand too, I heard it helps increase your hormones an vitams to help conceive. there's also "trying to get pregnant" stuff you can find anywhere like Walmart next to the tests.

we tried preseed for months with nothing. might try it again

it took us a year, & we had a loss in May. we tried pre-seed, & I got my bfp that cycle. - be sure to be actually tracking your ovulation too. not just going by an app. they were always wrong for me. they were right for an AF prediction, but wrong for ovulation.
