Help needed!

I’m 33 and TTC coming off the depo shot. My last shot was in July prior to that in July of 2014 I had a miscarriage and a D&C; followed. I’ve always been able to keep track of OV and AF with or without the help of using apps. I have 2 Kids and I knew a week prior to AF I was pregnant, now idk what’s going on I had a light AF from the sep 27- oct 3 then another from 19 oct- 25 oct. in between the two I had cravings, nausea, breast tenderness and fatigue and I still am. I’ve taken test but some are neg and others I thought I saw a vvfl. Idk if I should just keep trying or wait until my flow gets back on track.
