I had my first depo shot on May 18th I was supposed to go back to get my next shot on August 18th but I forgot about it and missed it. I have been having unprotected sex couple days after I missed the shot without realizing I had miss the shot. I started my period 4 days after missed shot. I am 20 year old who has uncontrolled type 1 diabetes and I am terridied that I could end up pregnant.
