5 days late

Hey all. I'm new to this app. A little short story about me. My name is Sarah and have been in a commited relationship with my awesome bf of 6 months. My periods have always been regular every 26-28 days lasting from 5 to 7 days. From my calculations on my calanders the day of my last period of Nov was Dec first so I feel I am due to start soon. We always used protection and are very careful. There hasn't been any spotting or anythibg like that As much as I love my bf and our life together I think we're not quite ready for that. I feel our relationship isn't quite ready for something. We discussed it and I know we'd still be together. Any advice and knowledge would be appreciate it.
