8 months trying any advice ?!

We have been trying to have as much sex as we can in fertile window

- but worried that should just be having sex every 2-3 days instead

But feels like it’s too much pressure now

I have periods every 28 days and usually LH surge in the 13th so thought would be ok to just do in fertile window

Starting to worry now and not sure when to go down <a href="https://glowing.com/glow-fertility-program">Ivf</a> route ?

I’m 33

Thanks!!!
