Leaving it late

Liz • Late in my child-bearing years I have met the love of my life and we are so eager to become parents.
Just wanted to say hi and see if anyone had any tips. I'm 38 and my partner is 40. We are both childless and after falling head over heels really want to start a family. We have been trying for 4 months but with no real urgency but we are beginning to get quite down when AF arrives. I need to step it up a bit. Any advice?
