Trying to conceive! need help!

Hi! My husband and I are trying to get pregnant. My cycle can be kinda wonky with ovulation windows and period coming late/early. It’s not uncommon for my period to show up a week after my app shows. I’ve taken tests on Monday and today; both were negative. Could I still be in early pregnancy and it not showing up on the test? Am I going crazy testing so much/ close together?😂Just would like some motivation for first time trying to conceive and not to give up this month.
