pregnant?!?

Caitlyn • Mommy to Liam 2.12.14. Due 1.9.18 with my 🌈 baby. Ryker Ashton 👶🏻
So... my period was supposed to come on march 9th. But it came on march 4th and it was super light and only lasted maybe 2 days. And now I am super nauseous and my back hurts so bad. Should I take a pregnancy test?!
