Me & My Boyfriend Been Ttc For Almost 6 Months Now, & My Period Has Been All Over The Place.. So I Found Out Every 17 Days I Get My Period.. Last Month & This Month My Period Has Been Messing With Me, & I Usually Bleed Heavy, But This 2 Months I've Been Bleeding Really Light... Am I The Only One Having This Kind Of Period?? I'm Getting Really Worried.. Any Thoughts Or Experience?
