Period/ovulation after birth control

Jessica

I’m trying to conceive my 2nd child and with my first child I got my period as soon as I stopped my birth control (Depo) but it still took us a year and a half to get pregnant but this time around I’m not ovulating or getting a period. I had my lost shot in May and then we decided I wouldn’t take it again and we would try but I’ve used hundreds of ovulation tests and nothing?!? Has anyone else experienced this or how long did it take for your cycle to regulate after stopping birth control?
