Depo Shot

Is anyone coming off of the depo shot? I took it for only a year and It’s been 11 months since I was due for my last shot ... we have been trying to get pregnant since July. I had a good period in May, June, and July but come August I would just spot brown when I was due to start my period and I would spot when it was time for me to ovulate.... and has continued to do that. I take prenatal vitamins. Take the ovulation tests... they’re all very faint - still negative :( I had a positive reading in October but I don’t take them very often. We try to be active every other day. It is completely draining. I’m loosing hope :( I wish I would’ve never taken that shot.
