ugh all 3 apps say different period times

one app says my periods due in 7 days another 12 and another 10. just wish i bloody knew what my body was doing. Not only is my cycle irregular, i don’t get EWCM during ovulation 🤦🏼‍♀️🤦🏼‍♀️ baby making it even waiting to see if we are pregnant has never felt so difficult and annoying lately. really regretting going on the pill because my cycles were perfect and i always go EWCM during ovulation
