I know google says up to 5 days but I can't find a study that gives a figure for the average life of a typical mans sperm.
I don't want to track LH or temp or anything like that, I had an early MC and I was pretty heartbroken by it even though it's my 4th mc. I am thinking sex every 2 days from around tomorrow until my period shows/ doesn't show up again. But with toddler/ work/ etc I'm not sure we will want to every 2nd day! Every 3rd might be more realistic.
My MC started on the 8th so I am counting that as CD1
