I've been sexually active all month not sure when I ovulate I was due on today and had nothing.. I took two clear blue digital tests both negative but I feel they may be wrong coz I'm eating more and put on 3 pounds in two weeks. I get a sicky feeling and even when I eat I want more. I'm not sure if I have other symptoms part from the odd occasion stomach cramps that go away.. I've been stressing a bit just want to know your experiences.
