when you do that, you have to let your body reasjust, and this takes an additional month after any change in your pill taking schedule. so yes, chances are pretty good you are pregnant.go buy an at home pregnancy test.it can detect the pregnancy hormone if you are about 4 or 5 weeks along at the earliest. my little sister got pregnant this very same way....she was taking her pill in the morning, then a couple weeks later she started taking it it in the evening, and 1 month later she found out at her checkup that she was 7 weeks pregnant.... i mean, the timing has to be dead on, but it is soooo poissible.pullout means nothing if your man makes precum.precum has sperm.sperm get you impregnanted. sperm can live for up 5-7 days in an optimally muscusy vagina (but usually only 3 days, because your body doesn't usually produce copius amounts of lubrication except when you're ovulating unless you are perpetually turned on). and you are ovulating typically for 2 days... you can actually feel your cervix inside of your vagina if you stick a finger in.there is what feels like a dent at the tip of it, or sometimes it feels like a hole you could stick a finger in.if you feel the dent, it means its closed.the hole means its opening and you are ovulating. so combine all these factors, and yes...there is a good chance that, in the window of a couple hours, you had been ovulating and his sperm that was already in you had made it to yours cervix, and then met your egg and won. buy the test...pee on the stick....and be certain.
