Frustrated!!

I wish our bodies could send us a notification like "hey girl, you're pregnant!" Or "Sorry hun, not this month you're period starts in a couple days". I'm sooooo tired of buying pregnancy test after pregnancy test! It seems like ever since we have started TTC every month my period has been super late!! It's so frustrating!!! I'm so tired of stressing every month and checking my cervix, basal temp, and all that crap!! Sorry if this isn't allowed I'm just frustrated and needed to vent.
