Lounge for some advice please

Hello so this was my first month using ovulation tests. My “surge” days were either CD 15 or 16 (although not detected by the app). From the chart and baby dancing dates I thought we’d have a good shot but unfortunately I just got my period today. I understand that just from planning baby dancing days around the surge it doesn’t necessarily mean you will conceive. I wondered if anyone had any advice or what you would do differently given my cycle and baby dancing dates?

My husband and I have both had fertility checks/sperm analysis not showing any abnormalities. I’m feeling a bit down with it all. Just looking for what you guys think and if there’s any advice you can offer. I’m thinking maybe we didn’t do the need enough? Thanks for help
