Hi its hard finding information on internet for 25-day cycles. My last four cycles lasted 25 days. Date of my last period was 31 Oct 2011 and I had unprotected sex on sunday 6 november (twice). i had very wet egg white cm on tuesday 8. any help with ovulation, how long sperm live and chances of pregnancy would be much appreciated as most sites are for 28 day cycles. before this i was as regular as clockwork on a 28 day cycle.
