Arrgh... went off the pill last August, only now settled back into a good pattern with periods every 28 days. So far so good.
But... my most fertile days are mid week! DH has to get up at five every morning for work and we both have stressful jobs that leave us knackered every day.
I have asked for DH's full assistance next time round... to try every 2nd day or so starting on the weekend and ending the next, but doubt we'll be able to make it.
I am 38, so not that much time left!
