hey i've been on levlen ed for 3 and a bit months. me and my boyfriend generally use condoms during sex even though im on the pill but sometimes we do it for a bit without. he's only ejaculated once without a condom and he pulled put just before but i want to know how effective levlen will be if he doesn't pull out. apparently its only 75% effective. what are the chances of me getting pregnant? i dont get many of the normal effects of levlen as in my period is still quite heavy, still get pretty bad cramps, boobs haven't grown, my skins the same. does it mean its not strong enough for me or im just unlucky? thanks in advance
