i cant concentrate my studies coz of im so worried that if i could get pregnant because on the 14th day in my menstrual cycle last week,i kissed my boyfried in standing position,then im afraid that i could get pregnant because his penis just like touching my uterus area(kind of),then my jeans and panties are wet,and there was like a little blood(brown-reddish).Of course his jeans wet too.Then there was time we were lying down and kissed,but our legs were sided way.Im so afraid if the sperm could climb to my vagina.Then I've searched the pregnancy signs,and some were like happening on me such as, breast pain,stomach gas,then i looked like my uterus area is like bigger,I don't know if im too stressed thinking about this until I don't know how my uterus/pelvic area look like??PLEASE HELP ME :'(
