i had sex with my boyfriend on june 15, 2009 we used a condom with spermicides but when he finished and pulled out the comdom stayed inside me, i took plan b the day after but did not take the second dosage on the 18th we had sex again with a comdom and spermicides and i took plan b the day after correctly, ever since ive been having minor disconfort on my stomach or minor cramps, i pee a lot, im bloated and very anxious, and ive been really tired, may i be pregnant?
