tips on how to get pregnant ?

I’ve been trying for 4 months to get pregnant (I know it’s not that long) but haven’t got anything yet. i was over 15 days late in April and got really excited then i got my period. this month so far I’m 6 days late but 2 of those i spotted a tinyyyy bit of really brown blood but only in the morning when i wiped. any advice/ tips you could give me it’s my first time trying and don’t know much. Anything is appreciated!!
