hi somehow you 4 years adrift or have lost 4 years but if your on the bc pill as you say and a normal pack is 28 days of which the last 7 are placebo's which turns on your period. so all being well you should not get pregnant during unprotected sex. now the negative side is about 1% can get pregnant why on the bc pill but as you say you have pollicystic ovaries that like having your own back up plan women with them find it hard to get pregnant. does that answer your questions? good luck ps if you want anymore just come back through answer this above.
