trying for a baby is so hard

ch
I've been off birth control for 2 months now and have been having sex almost everyday with my partner (apart from the days I'm on my period). Unfortunately I haven't been able to get pregnanct. My period is meant to be due on Tuesday and I've had constant heart burn and stomach cramps, and for the first time ever I've had spotting before my period. I took a pregnancy test this morning and it came back negative. I was so confident that i was pregnanct but seeing the negative sign was really a kick in the stomach ☹️😭 are there any tips on enhancing getting pregnant? Starting to lose hope.
