I have been having pain in from my belly button and down. Urinating more than usual. Brown spots or stains in my underwear. Headaches for like 3-5 minutes. He said he pulled it out, but I think I felt it going doen between my legs past my vagina. It was cold. My period is 3 or 4 days, but it flops around though. Could I be pregnant?

Take a test, could just be your body changing due to stress, diet or other lifestyle changes

Is it too soon to take a test?

You need to wait to see if your period comes when expected before taking a test.

Ny period is late. It normally comes on the 7 or around that time. I've been having stomach pains like crazy.

If your period is late take a test. Any time you have sex you could get pregnant but no one can tell you if you are or not.

Make sure it is with the first urine of the morning.

But yes of course you could be, you had unprotected sex. People that use the pullout are normally called parents soon.
There are sperm in the early fluids, often they don't pull out fast enough and only some come out, and often they can't control well and stay in.

So use condoms and get on birth control pills if you are going to be having sex.

Thanks. I'm about to take a test.
