okay, exactly 11 days ago (July 4th & 5th) i had unprotected sex two time with my boyfriend, technically both on the 5th. once at 4 in the morning, next around 1 or 2 pm that same day. i'm young and i don't have regular periods like i should so it's hard for me to be able to tell when i'm ovulating, but from my last period ( June 20th) i did an ovulation calculator and it said that would be the day i was ovulating( the day i had unprotected sex). anyways, since a few days after we had sex, i started having symptoms of feeling naseous, my nipples being a little sore, some cramping, excessive fatigue like never before, i felt like i could sleep all day. having to pee often, but i think that was all in my head. dizziness on occasion, and some really bad food cravings. all that lasted for a couple days, now it's day 11 since i've had sex and i had only a little pink blood, only when i wiped this morning and then i got nothing but dark brown with a little pink/red blood in there. and it hasn't been a large amount. i can't tell you when i normally have my periods, because sometimes they are scattered out and sometimes i dont even have a period one month, i might skip months..which i dont think is normal for me being 16, when i started when i was 12. but i just really want to know, am i pregnant? i'm afraid to go buy a pregnancy test, because a) i dont want my mom to find out, so how am i supposed to get to the store to get one? b) i dont have the money for it. i just really want some honest opinions on what i should do..if i should work my way around getting a pregnancy test and test it out, and if so..can i still do it while i'm bleeding or having brown discharge? should i wait until the end of the month to see if i have a complete period? how does implantation bleeding work? i mean, i have so many questions..i'm just young, and i should be watching what i'm doing..it was my first time, and i didnt think about everything thoroughly. please can i have some advice anyone, and don't give me anything that says "you should have used protection" because i know i should have..but i didnt, so give me a little more helpful info please. btw, i'm not on insurance..so i cant go to the doctor about any of this.
