I have ovulated bc I had clear sticky discharge w/cramps, now its yellowish white, still cramping with leg aches, could I be pregnant?

Check pregnancy test. The great thing is that pregnancy tests are available at any pharmacy so you can have an answer in minutes and then you wont have to worry about it. Yellow discharge, cramping and leg aches are not symptoms of being pregnant. The yellow discharge needs to be evaluated by your doctor for infection.
