So confused!😫

Lilli • Mommy to Princess Bryleigh<3 blessed with an amazing FIANCÉ!!!<3 I love my little family!
Okay ladies I'm in need of help please!
I started my period May 21, after not having one for 2 months.. I'm on birth control so this isn't odd. But I'm having 2 issues that are confusing me! 
#1- okay my periods generally last 6-7 days. This one last 6 days but after that I've had light to medium spotting and passing clots the size of a quarter sometimes. Does this still count as a period or is it spotting? Please explain if y'all are able! 🙁
#2- the last several times I've gotten my period it feels like my lady area has been scalded. It burns, and itches like a year infection. But SO and I don't typically engage in sex during my period bc it gets me pretty badly. So I'm so confused as to what's going on. Why does it feel like my period is burning my area? 
Thank y'all for any and all help y'all can give. It's greatly appreciated!❤️
