I feel really silly for posting but this is still driving me crazy so here goes. The past few months (atleast since I have been recording it) I have gotten AF at exactly 27 days and always somewhere in the middle of the day. Well here is is day 27 at midnight and still no AF. The thing is we didnt BD but once...and that was just on Friday the 3rd (today is the 6th) So did I just screw my cycle up, or is there a chance I may actually be pregnant? (All of three days pregnant!) What do you think? I know I will regret posting this and probably get my period tomorrow, but it still has me puzzled! (I am nursing but our schedule hasnt changed any at all) Now I just have to wait....grrr I hate waiting!<br><br>
Someone please just smack me and tell me Im crazy. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">

OK with a 27 day cycle, you *probably* usually ovulate somewhere in the middle of that. Most people with a regular cycle ovulate 12-14 days before AF shows up. Your most fertile period is the 5 days leading up to ovulation, and after ovulation you are infertile because the egg only lives for about 24 hours. Sperm can live 5+ days in there if conditions are right(eggwhite cervical mucus), which is why intercourse on the 5 days preceding ovulation can result in pregnancy. I've heard of people getting preggers from doing it more than 5 days before ovulation, but that's seriously rare.<br><br>
So, ASSUMING nursing is not shortening your luteal phase (as it very often does) and you're ovulating somewhere around Cycle Day 13-15, your most fertile period is *probably* CD 8-15. Intercourse on CD 24 is extremely unlikely to result in pregnancy, unless you did not ovulate until AFTER cd 24, in which case your cycle would end up being 36-38 days long if you had a fertile luteal phase of 12-14 days. (a luteal phase that is usually 10 days or less needs to be treated, because it takes 8-12 days for a fertilized embryo to implant, and a short luteal phase can make AF start before the baby gets a chance to snuggle in and get setttled. This is why I am taking b-100 complex every day, and keeping fingers crossed my LP goes up to 12 days this cycle!)<br><br>
Does this help? Or is it just WAY more than you ever wanted to know? LOL!<br><br>
