Pull out method or cycle tracking as birth control

okay... so my husband and i have a 13 month old, we really would like to wait until atleast she's 1.5 years to get pregnant (we are like if it happens it happens if not then the bigger the age gap which is fine). I've noticed my husband making comments that suggest he's tired of using condoms and honestly when we are out and can't have sex it's a real damper on the mood. I am not on birth control pill or IUD d/t health reasons so condoms are out only choice. Am i asking to get pregnant practically if we use the pull out method and just cycle track? Like if we had sex without condoms before my predicted ovulation and closer to when my period starts and then just use condoms when i'm ovulating? has this worked for anyone or did you fall pregnant? lol
