Could I still be pregnant ?

Hey ladies, for the mamas out there is there anyway I could still be pregnant even after having my period ? Me and my husband tried this past cycle and when my period came I was heartbroken. (It felt like a regular period) It’s been a week since then But lately I’ve been having funny symptoms like fatigue, nausea in the morning and a crazy daily headache.

My best friend said she got her period two weeks before she found out she was pregnant. Has anyone else experienced that?? I want to be sure before I waste a test on false hope.

Thank you and baby dust to all 💖✨
