Hi, i came off the depo last year, my last injection was July. I should of gone back 1st Oct for next jab, but i want to try for a baby so didnt go back. Since then i have had no period, just pains, aches, cramps. I have been to the docs and had swabs but all back clear. I would just like to know why i get period cramps but no period? And is this a sign that my periods will and my ovulation will return soon?
