hey, i had my last period on the 16 th of july and i was late . before i had my period , i did not have sexual intercourse but i had sexual contact by means my boyfriend tip was outside of my vagina but was not in. however after i had my period i was experiencing symptoms such as sore breasts , puffy aerolas, and erected nipples. i have also gained weight. now my period is due in about a week and im very very worried that i am pregnant. ive taken pregnancy tests and they all have came out negative. my breasts have been sore since i finished my last period and it is still sore now. is it possible for someone to get pregnant this way or am i just overthinking? i am very very worried as i am still young. if not possible why am i experiencing symptoms like this?
