Chances of being pregnant!?

what are the chances of me being pregnant. my period is very punctual every month and it never delays for more than a couple of days. I had my last period on september 22 and counting a 28 day cycle it would have been here by oct. 19. but nothing. I did...

have unprotected sex various times within this time period but he never eyaculated inside me. I took two pregnancy tests about two or three weeks ago the first one came out negative and me wanting to be sure took the other one the next day wich came out negative as well. I havent had any symphtoms other than more gas than usuall wich I dont know if is really a symphtom , also I've lost my appettite and sometimes the smell of food doesnt appeal to me but I dont get nauseous. I've been a little stressed but not more than the normal. now I dont know what to expect I've talked to a couple of friends who've told me that mybe it was too early to make the tests and thats why they came out negative. I've also been really sentimental and crying a lot. so I was wondering if anyone could tell me how much chance do I have of being pregnant and yes I am going to take another test as soon as I get the chance but for now I wish someone could give me some help on what they think.

your could still be pregnant due to pre-ejaculation. sometimes sperm comes out before and even if your boyfriend DOESN'T ejaculate inside of you, he could of still got you pregnant. that's why the pull-out method, or taking the penis out of the vagina BEFORE the guy ejaculates isn't too affective.
the reason why the test could could out negative and you'd still be pregnant is because of the pregnancy horomone HCG. you have to wait a couple of weeks until enough of it is built up inside of your body to be detected by a test. you could also go to a doctor, they can detect pregnancy MUCH earlier, even if you dont have enough HCG yet.

good luck=D

Agreed with lovestruck. Depending on the brand of the home pregnancy test, you can take the test as early as the first day of a missed period, or 5-7 days or longer after a missed period. Always read the instructions on the test. You can go to the doctors for a blood test to know once and for all, although I think your stressing from thinking that you're pregnant is delaying your period even further. So try to calm down.
