Two months late, inconsistant with my pills...pregnant?

Hi, um well I am 18 years old and a senior at my high school and me and my boyfriend have been active for awhile now, in the beginning we used both condoms and pills, but in about January I became inconsitant with taking my pills, forgetting to take them...

2, 3 days at a time, and stupidily also started slipping on using condoms too( yes, were both stupid and lazy, we know), he didn't c*m inside of me he pulled out, but I know from health class that pre c*m does contain sperm..
Its been two months since a seven day period, a week or so after we started "slipping" I began to have spotty bleeding and some pretty hardcore cramps, also now its been about 4 weeks and I've been feeling nauses although like staving all the time, I've had some pretty bad headaches, some tenderness in my nipples, mood swings and also some pretty gross smelling discharge, I'm not quiet sure though...
Help?

all the things you just said was signs im sure your pregnant

Well, the only way to tell if you are pregnant or not, I suggest you get a pregnancy test. If you ignore it, and you are pregnant, its better to just find out than wait =]

You ARE pregnant. I'm not sure whether I should congradulate you or not. Mistake or not, your baby is still God's creation. Congrats!

Take care of yourself.
