Sister in law got pregnant taking birth control pills

[toodles29]

My sister in law has been on birth control pills for one year but she just found out she is a month and 1 week pregnant.  How is this possible?  She told me she never skipped any of the pills.  I took birth control for 2 years and of course I never got pregnant.  Does anyone know why it works with some peoples bodies and then others it doesn't?  Just curious.

It is not enough to take the pills each day--they have to be taken within 4 hours of the same time each day.  There are also certain medications that can interfere with the action of the BCPs.  

If a person is obese, also, there may be issues of effectiveness.  It is extremely rare for a person who takes it exactly as prescribed, who gets pregnant.  But it certainly can happen.

One of the biggest factors pills can fail is if they are taken in conjunction with certain diet pills as well. My SIL got pg because she was taking her BCP with Metabolife, causing her body to metabolize the pills at an accelerated rate.

But by far the easiest way to screw up pills is like Christie mentioned, by nor taking them close to the same time daily. One friend of mine has 2 pill babies due to this very reason.

Best to double up on BC methods if you are adamant about not being pg.

NO, she is not obese, quite the opposite short, petite and good figure.  I know she wasn't on any medications and as far as I know she has taken the pill in the four hour window.  My mother in law was the same way she got pregnant while on the pill as well but that was a long time ago.

Hey!  Yep, i'm 29, ttc for the first time.  my periods are always the same whether i'm on the pill or not, i get spotting for a bit...the next day is full out heavy...then it lightens up and by the end of the 3rd day is basically gone.  3 days, thats it.  I stopped taking the pill about 10-12 weeks ago and have had one normal cycle since.  I THINK i ovulated this weekend because I could feel the pressure in my lower right abdomen, but really, who knows.  I am so out of touch with what goes on inside of my body its unreal. you'd think after living with it for so long you would know everything.  Tell me more about you, when you get a chance.

If anyone can tell me what it feels like to ovulate, can you let me know...like i said, i'm pretty dumb when it comes to this kind of thing.  OH and also, the cm, does it come out on its own or do you have to go and get it to see if its stretchy.  I don't remember EVER having this.

With our first child, I was on birth control pills (ortho-tryclen) and I took them at the same time everynight before I went to bed. Well, after 8months of taking them, I became pregnant with our first son. My doc says that every woman's body is different and some just can't take bc pil.

I too got pregnant with my first while on triphasal. Took them every day but I was dieting and drinking tons of water. I think I flushed them right out of my syste. What a shock that was.
