I have missed a depo shot and was reschedule for another on July 8, I had no symptoms or period in the month of June. I had unprotected sex on July 1st started the 3rd I had brown discharge for a day, from then to today I ve had discharge, cramping, wanting to vomit but I stop myself, tired, hungry more often & a lot more thirsty! I usually don t cramp intel the day before my period but I ve been cramping almost every day, I m always every emotional, idk if it the depo withdrawls or pregnancy I ve took 8 test & all negative in the last 2 weeks next week will be week 3
