I've had a pink discharge 2 days ago which was day 14 of my cycle.. in now got cramps in my lower stomack.. could I be pregnant?

It may be due to ovulation. If you happen to ovulate early in a cycle, it could be from pregnancy. It may just be from a fluctuation in hormones.

You'll need to wait until you are close to when your period would be due to try a test. Even better would be to wait and see if your period doesn't show when you expect it to.
