Hi, I've just had sex with my boyfriend today and i am already on the depo and had to wait a week for it to work, so last week i got my injection done and when me and my boyfriend had sex we used a condom which didn't break. however, he pre ejaculated but some might've stayed on his male parts which stresses me out. he did not ejaculate in my vagina. as this is the first time having sex, i am very very scared and i wonder if i'm pregnant as i'm not sure if i could have sex and if i should've waited longer for my injection to properly function. Any help would be appreciated. thank you very much
