For days i've been searching for an answer to find. the answer to a question that has been steadily on my mind...

so my boyfriend and i had unprotected sex (yes, i know, very foolish and very irresponsible, but it happens)...i guess the reason why i actually went through with it was because i was supposed to get my period the next day, so i thought, hey nothing could happen if i'm gonna get my period. i'm pretty sure he didn't cum inside of me, nonetheless there is always the risk of pre-cum. so the next day came and i didn't get my period. it wasn't until the next week that i had a super light flow. i'm usually heavy during my period. and this only lasted maybe 4 to 5 days. i didn't feel any cramps AT ALL, no pain no thing and it was super light, like i didn't even need a pad. since that date, which was back in june, i haven't gotten my period since. so technically the last time i had my period was may 6. the latest i ever get my period is by the 10th. we are now at the end of july and i have not had my period. about a week after i was supposed to get my period in june i took a pregnancy test and it came negative, and i took another home pregnancy test about a week ago and it still came up negative. i don't know whats going on, and i know i should visit a doctor. but any opinions/suggestions/advice would be greatly appreciated. 2 of my co-workers even told me that i had put on a little weight around my belly, i didn't really notice it. and at times i feel like i'm gonna get my period.. but it doesn't come. and its frustrating and confusing because i don't know whats going on and right now i just need a piece of mind because maybe one of you have experienced this or might know a little as to what i'm going through...

..... i might be pregnant
