Most of you girls seem to monitor your fertile times (checking Cervical mucous, temp, etc..). I must admit I do pay extra attention around the middle of the month.

What about the theory of just going for it every second day throughout the month? Personally I just don;t have the energy for those shenaningans so often (with full-time work and very full-on nearly-5 y.o.). However surely given the length of time that sperm is able to survive, bd'ing every other day would (eventually, based on probability) do the trick? I know it seems a bit simplistic but...?

Thoughts?
