i played with my boyfriend on 14 august. he rubed his penis on my vagina but never penetrate me with it bc i am a virgin. we masturbated and penetrated with a finger. it is possible to be pregnant? had my periods on september, obtober with 5 days earlier, november with 3 earlier. but my cycle used to last 5 days and now it lasts 3. so i am freaking out. i made urine test and came out negative, blood test also neg. but i had pains in the lower intimate part. so i went to gine. i am practicatlly virgin so check was not possible. he did an echo and said that the uterus was normal. he gave me urinex and uriflow for a possible infection. but i feel my belly strange as if it had grown. it may be just my imagination but i am very scared. my period has to come in 5 days. what should i do? what if i discover it too late?
