I had sex with my boyfriend about 2 weeks ago. I think we did it about four times that week (yes, i don't know what i was thinking then). last time we had sex then was Friday but he never did ejaculate inside me. Every time he felt he's getting too "tickled", he pulls it out and ejaculate outside after minutes because i bj him.

I know i could still get pregnant if this is the case because he doesn't know if he pre-ejaculate inside of me.

now, by some circumstance i was forced to take a pregnancy test Saturday after the last 5-minute intercourse we had (which was the day before, more than 24 hours later) with the same situation i stated above, only, he did not ejaculate anymore this time. I had a test in a hospital because i'm a part of a research they're doing there. The result was negative.

Now (after 2 weeks), i still am not having my period. I think i'm about 2 or 3 days delayed (i can't remember the last day of my last period....). could i be pregnant? or am i just paranoid?

i admit that i am stressed out these passed few days. this is one reason for it.

but i get more paranoid because when i did research about this stuff, i found out that when one is pregnant, frequent urination is a possible symptom... and i am urinating quite frequently these past few days.... help me guys... i really don't know what to think now... i don't want to be pregnant!!!
