Could I be pregnant ?

Jennifer • 23, Married to the LOML👩‍❤️‍💋‍👨 Mommy to a princess 👸🏼 & angel baby 👼🏻

I usually have a 7+ day period. We had unprotected sex July 4, my period came only for 4 days or what I think was my period super light bleeding nothing like what I usually have. Very bad head aches. Back aches. Stomach aches and a little cramping. I’m honestly scared to go to the doctor. Has this happened to anyone else?
