Depo injection & TTC :(

I was on the depo injection for 4 years. I came off it January 2018. Been TTC sinse so a year & 10 months now. I’m just wondering what other people’s experiences were?? My periods took over a year to become regular, a few times I thought they were back to the same time every month for it to then mess up again (last time being July this year) so far the last 3 have came bang on time :) I’ve started taking 7 seas last week & using ovulation sticks so hoping I’m not waiting too long. I know it can take up to 2 years after being on the depo but it’s just getting really frustrating. Not sure if it’s worth going to the nurse now
