I'm bleeding light pink with brown and white discharge as well and I have been cramping and moody and my breast are tender I had unprotected sex about 2-3 weeks ago could I be pregnant?

When is your period due?

We really can't diagnose pregnancy online, we can't even guess. In order to diagnose pregnancy we'd need your urine, your blood, or an ultrasound in later pregnancy. Since we can't access those online, it's up to you.

Wait until your period is at least 2 weeks late, then take a pregnancy test using first morning urine (the first pee of the day). If that test is negative, wait until your next period, and if that's missed, test again or get a blood test.

The only thing I can tell you is that it's possible that you're pregnant. You had sex. You had unprotected sex. So there's definitely a chance of pregnancy.

Good luck.
