Fertility Friend is pretty good with giving answers you are looking for. Super sperm can live up to 4-5days.

A similar moment to what you're experiencing now resulted in me joining the TTC band wagon. Haven't experienced the joys of motherhood, but it made me realise how much I wanted to experience it.

Its hard when each others (DW & DH) wants/needs don't match up, I would love to have 3 children... only time will tell - have to have one first

All the best
