Chances of getting prego the last day of period...And buying EC pill during the weekend?

Question

Ok first question, my fiance and I had a little accident (the condom broke-ripped down the side) I thought I was through with my period but actually it had just slowed down b/c it was almost the end, and I started again after the sex.....What are the chances of being prego? I found this ovulation calender to gauge it kinda but it completely lefted out the 12/13, what does that mean
MONTH 1:
12/10/07 - First day of your cycle
12/21/07 - A little bit fertile
12/22/07 - Fertile
12/23/07 - VERY fertile
12/24/07 - Time to ovulate
Second question....I live in a really small town and I wanted to get the emergency contreception but couldn't get ahold of anyone to get it and its friday and now everything is closed till monday--and you only have 72 hrs to take that pill for it to be effective.....Since its available without a prescription and Im 22 can you get that pill at pharmacies at walmart ect?Or any other places to get that? (Dont lecture me please just answer ?or move on Thanks)

Answer 1

Its highly unlikely that you will get pregnant during your period. Day 1 of the cycle is the day your period starts, as you see it is about 10 to 11 days later that you start to have a chance of being fertile.

Plan B is tough on your body; since the odds of being fertile are remote I wouldn't bother with it.

Answer 2

means you are next to not fertile at all until 11 days after the start of your period

honestly, I know it's you and not me, but I wouldn't even worry about emergency contraception. Despite what the safe sex preachers would leave you to believe, it's actually pretty hard to get pregnant. If you're fully inseminated on your most fertile day of the month, you only have a 33% chance at the very most of getting pregnant, and there's only about a 6-7 day window that a woman is typically able to get pregnant. Outside of that window your chances are GREATLY reduced. If you have unprotected sex enough times though, you will eventually get pregnant, just don't make it a habit.
