Depo shot & TTC

Hey ladies, I'm TTC currently! I was on the depo shot for 3 years. I've been off the depo shot for a year now and been having unprotected sex. It's a little frustrating, but I know the medicine from the shot stays in your body a little longer. Recently, I started losing weight and eating healthy. I've been tracking my ovulation and having sex during that time.. I saw a lot of you recommended Preseed Lube.. any other suggestions?? TIA, baby dust to all 💗
