Maybe?

Savannah • I`m 18 years old trying for my first! Taken by my wonderful man
I have a normal 28 day cycle. We had sex on the day of, & days before and after, ovulation(June 9th). Since then, I've been more hungry, tired, & even nauseous at times. Af isn't due for 9 days. I'm almost scared to ask: could I be??
