I am 6 days late on my period. I'm 21 years old and my periods aren't too regular (some times they're 29 days, sometimes they're 31 days). The day of my last period was Nov 14 and I ovulated on Dec 5 and still have yet to get my period. My boyfriend and I have had protected sex AND he has pulled out carefully long before he had to go (meaning he had enough time to take the condom off and stimulate himself far from me). We've always checked each condom with water to make sure there were no leaks and have never had a problem. I was really stressed during finals week last week and now I'm worried about why my period hasn't shown up when expected (I expected to get it Dec 14 and today is Dec 19). What are the odds that I am pregnant, even with the methods my boyfriend and I practice (condom and pull out way before ejaculation)? Please help :(
