Help lol

Jennifer

Hello I’m just been overthinking about this . I’m not too sure what to do . Usually I start my period on the 10th or 11th but this month it didn’t lol I’m not sure maybe I’ll start late or I could be pregnant. I’ve been having symptoms like headaches and tender breast and mood swings and cramping but nothing. Today I’ve been having stomach cramps and lower back pain but still nothing 🤔 oh and I also had unprotected sex January 28th . Maybe I should wait for few days to see if I would start before taking a test? Or find out now ? Pls help me out by giving me advice thank you🙏🏻
