I'm new to this

Samantha • Me and my boyfriend have been together for almost 8 years we have 2 kids together and ttc #3 after a MC 🙏🏻👶💗💚💙
Ok so I just stared using this app and I know what TTC mean but not any of the other ones o see on here And I don't know how to change the time of my cycle it says it's 4 days long but it's really 5 days long and I know that makes a difference
