Ttc #3 after depo

So Ive been on and off of depo , I took 1 round then ttc for 3 months and gave up (during those three months I took natural remedies and got my period and even was ovulating) but nothing so I went on the pill 3 months then took another round of depo , then I got my period around the time depo was due and decided to keep TTC #3 . but now its been since September I haven't gotten a period about a week ago I had all PMS symptoms mild cramping and yet no period, I've taken pregnancy test and all negative I've been checking cm & bbt my temps dropped 10,days ago for one day then went back up , yesterday(9days later) my temps dropped again and today raised back up. My breast have been feeling like I need to breast feed ( my kids are ages 6&4) so I'm all moody because I feel that I'll never get pregnant and not even with the remedies I tried before have I gotten my period this is all weird for me , I've had excessive white cm but I'm not pregnant stupid depo
