Hello I'm Very Concerned I Have Had The Depo-shot For

Hello I'm very concerned I have had the depo-shot for birth control for nine-ten months (the one you have to renew every three months) and I didn't renew it on may 26th when I was supposed to it has now been two months, sex is very painful, I'm getting random very very small (almost blemish frecklish) bruises on my thighs, my allergies have gotten a lot worse I break out in hives almost daily. I have yet to have my period, I'm not pregnant, my urine smells really weird and I have brown vaginal residue. This has never happened before? I also have migraines where my vision goes out, and I hear ringing in my ears.?
