Help Me Please Iam Soo Desprat I Need Advise

Hi everyone..

Iam scread out my mind I think I may be pregant and the bad thing is.. That iam only 16 years old, iam not ready to have a baby I really need someone to talk to someone in the medical felid to help me out... I fill you on the details and you tell me if you think I am pregant.. Well first of all I had my period for the first time in august 20 or something like that around 10 pm at night, now this happen the august that just passed I had it for the first time in my whole life. Then I did not have my pd at all in sept. I guess I skip a month I dont know why... Then I had it again on oct 01 or 02 I can't remember and it ened around the 9th or 10th iam not sure... But any ways and then it the 3rd of nov and I still dont have it iam going out my mind I think maybe it my first time that I may be skipping another month again or something like that iam not sure, but anyways around the 12th and 13th of oct. I kinda "messed" around like I did not have sex but I tried like to lose my virginty to someone, that person is not important at the moment but anyways I tried to have sex with him for those 2 days, nothing it was too painful to bear soo I stop even tho we did try for two days, the farthest he got was about 2 incs or maybe more I am not sure,ok so anyways it was around the 12th or maybe earlier iam not sure I think it was on one of those days well anyways I waited 5 days after my period to do it I dont know why it not like I really waited but like it happen 5 days after well anyways then we tried for the first day I would say it lasted for a good 15 mins like I was fusing around alot so it was not like we was trying for 15 mins it was like he put it in I scream and pulled, but he did not put it all the way, so this happen for about 2 days, trying to do it, and I know a female ovulates every 14 days, so if he did pre nut which I have a feeling he did not, but anyways I know that sperm can live in a female for 7 days so if it was around the 9 my pd ended then it would br the 22th I would ovlate right? And the sperms would have die before that right? Because it happened around the 12 and 13th that gives then about 7 days to live so they would have die around the 19th almost right? But anyways. I not sure because iam getting knews to my pd and I have not gotten it on the 1 or 2 which I think I was suppose to I did not get it at all and iam very scared. So yesterday I went ahead and took a prencgy test. It came back negative but I still worry because even tho it said I was not pregant I hear that sometimes those tests can be wrong it self. Do it sound like I can be pregant? Can you please help me figure out what to do, and oh yeah not only that like I been feeling sick like I want to throw up alot not really but like nauses and like I have alot of cramps which I hear pregant people dont get, I was really hoping that it may be my pd, but the funny thing is, like when I think about that fact that I may be, I get sick and I dont feel good, like iam stressing my self out, and I was told that stress can delay my pd, is that true.? I mean can that really happen I hope not, but anyways, tell me what you think. I mean to sum it all up. I took the test yesterday and it came back negative.. It was not the expenise test it was a $2 one. I mean can that be wrong. I going to take another test soon just to be on the safe side. What I dont understand is if the test said iam not pregant then why my period never came? Could it be that iam just late or that iam stressing my self to much and it delaying my pd? Or is it that there something wrong with me? Could u miss a whole month again.. And have it next month... Can that happen to me again? Please help me out iam soo scared I dont know what to do.. I know I cant afford this baby I dont know how to take care of it, the father is not even talking to me because I told him the story and how I think I am, he just keep saying we did nothing and that he cant possibly got me pregant. Anyways iam just on my own, it sounds like he wants nothing to do with this. Even if I am, I am not keeping it, I just get a pill to kill the baby. I know it sounds wrong but I cant afford to take care no baby. Please anyone if your like in expert in this type of things and you know what your talking about. Please help me. Cause I am scared. Either this baby goes it I am pregant,... Or .. I go... Iam I dont want to die.... But if I have no other choice I gonna have to take it. If my mom and dad know that I might be pregant they're going to kill me and I will die, or they will kick me out the house and out of my family. I have no where to go and no one to help me, so please help. And explain what might cause all the pain if you think that iam not pregant. I mean can it me that I am starting my period. Well you tell me please asap I need some perffsioanl help. If your really good at this then please tell me what you think. Thank you
