i had sex for the first time a few weeks ago, used a condom. then i had sex each night for the next 4 days, used a condom but one night while i was being fingered im afraid some of his precum was on his finger when he went inside me. thats why i took plan b a week ago, 4 days after that night. i know plan b can mess with your period and delay but i was expecting my period soon and never got it then i realized today that my vagina is white inside, it doesnt ich. it looks unnatural, i think its a yeast infection. im stressing because i havent got my periiod now in over a month, i still think i could be pregnant and now i have a yeast infection and i wanted to hav sex again this weekend. im not on birth control yet and have only had sex with the same partner.
