sore vagina?

Lexi
Okay so I'm just wondering if anyone else has ever had this and if either of my reasons could be a possible cause. 
So 1) I'm in my fertile window so I'm wondering if that has ever made anyone feel kind of sore down there. Sometimes my period does, but I haven't noticed in this time frame before. 
Or 2) I've been using dilators every night for the past month because my boyfriend is coming to visit soon and it's always hurt me to try to have sex. Anyways I took last week off because I was on my period and so last night was my first time using them again and I made it to level 5 (usually only get to 4) does anyone know if that could be why I'm sore?  
Thanks in advance😊
