Trying to conceive

My husband and I have been trying to get pregnant for a little over a month now and even though they say the average women doesn’t conceive until 4-6 months of trying, I’m still getting a little discouraged. I just got off my iud in July and I got my first period back just a few days ago. It was heavy bleeding the first couple days but has gotten lighter. I am on pre natal vitamins and try to do things can help my health. My family doesn’t have really any history of infertility, a few cousins maybe, but that’s it. I have always been afraid of being infertile and I really hope that I am just overthinking things considering I haven’t been trying for very long, but it is still upsetting. Does anyone else get this feeling? Is there something wrong with me? Im stressing out.
