Discouraged TTC

I had my period on the 9th of September and ended the 16th. Me and my partner have been trying to conceive for about 6 months and nothing. I got off depo the last day of march is when they told me the shot(depo) ended. Ive been trying to be sexually active as frequently as possible especially around the time my period tracker says im supposed to be ovulating. I dont have kids but im patiently waiting to get pregnant. Im always have the thought in my head if im even able to get pregnant. Any advice? Not getting pregnant is really making me emotional.
