Advise? Tips? Anything?

Hi everyone! My hubby and I have been ttc for 8 months now. This last month I was late, but kept getting negative pregnancy tests until eventually Aunt Flo came to pay a visit. I’m pretty disappointed as this was the first time I was late :(. I’m pretty regular, I’m using ovulation tests, and I lay flat after bd. Does anyone have any suggestions to help us conceive? We haven’t seen a doc yet, I’m hoping some otc remedies will help but I don’t know where to start... thank you all!!
