38 ttc baby #2

I'm 38 and will be 39 in August. Ttc baby number two. Been off the pill since January but only really tried in my fertile window for two months. My son will be 3 in September. I was 35 when I conceived him and got pregnant within two months of trying. I'm really nervous and scared that maybe I waited too long this time. Do I still have a chance to conceive? I have regular cycles.
