As if there weren't enough silly people going about thinking that their babies fetuses were full-fledged humans, there's now count-down tickers you can put on your blog that count how "old" it is and in what stage of development. You'd think that a ticker with milemarkers such as "my spine is growing," "my lungs are mature," and "my brain is growing fast," would not convince people of the humanity of feti, but ...


Our hand-drawn pregnancy tickers are ideal for modern parents to share the progress of their pregnancy.

Yeah, I do know redundant birth control can fail. I know my statistics. ;) But it's less likely than when using just a single form. In fact, I can tell you precisely how much less likely, as I just taught percents today and my birth control pills come with this nice and handy chart.

In one year of using condoms only, perfectly, 3% of women get pregnant, or typically 14%. One year of the Pill only they say 0.5% w/ perfect use and imperfect isn't listed. I'll make up 2% for my next stage of math. Assume the two are independent. To get pregnant using both methods, BOTH would have to fail. With perfect use, that would be 3%*0.5%=0.03*0.005=0.00015=0.015% chance of both methods failing. With typical use, 14%*2%=0.14*0.02=0.0028=0.28%, or just over 1 in 400. The chances of accidental pregnancy go from tiny to insignificant which makes me really shocked it happened to you.

I'm risk-adverse which is what led me to want to have the backup. Additionally, I'm intermittently on antibiotics for a skin condition, and they can decrease the effectiveness of birth control pills, so maybe I feel the condom's the backup for the pill? Yeah I know it's not perfect, but after getting out of college I realized how lucky I was that I didn't get pregnant with my first boyfriend. Withdrawal has a 4% pregnancy rate ideally, but 19% typically. Each year I had an 81% chance of NOT getting pregnant, so after two years of dating we had a 65.61% chance of NOT getting pregnant, or 34% chance that we would. I knew better, but I was sexually naive.

As a side note, I hope you find the humor in this statistical thought that crossed my mind. I wonder what percentage of people are pathological liars? If that percent's higher than the chance of you and your ex- having two forms of birth control fail simultaneously, then Occam's Razor says you were probably fibbing. Either that or you were nymphos, as the statistics don't account for frequency of sex. ;)

Actually very frequent sex reduces the chances of pregnancy. I think the sperm don't have time to reproduce or something. I know they tell couples trying to concieve to resist the (logical) thinking that they should just be screwing non-stop.
Before the pregnancy happened it used to be a joke between my friends and I wondering if there were any little Billys out there. Now I wait for an army that looks like me to rise up.
