I think me an my bf are both secretly trying

I never wanted a baby til i knew my bf wanted one so badly whike i was on bc or say i want to get back on he acts like it no big deal but everytime i get my period he gets upset nd everytime i throw up or hungry he excitedly ask, do you think ypur pregnant. Now ive been off depo for 5 months and and got 5 apps, and getting dissapointed too when my period comes because i secretly wanna give him a baby so bad. Idk why we just dont tell eachother
