E.I.
talk to your doctor, or any doctor, about natural family planning. it is a system that is 98% effective (which isnt any worse or better than any other method, and guess what? no worrying about if you have the supplies!)
it might seem more scary, but i know personally a family who tried it and it worked perfectly for them. i myself am going to personally investigate this in a while - im talking with a doctor now.
if your doctor wont talk about it, find one who will. its funny; i didnt think those kinds of doctors existed at the clinic im at until i happened to run across one by chance. they are hiding in there!
ive heard the best way to find out is to interview doctors. :):) good luck
