TTC year #3, and frustrated!

So frustrated!  Sharp pain on left side on the 4th and EWCM.  Then sharp pain again on left side and every morning GLOBS of EWCM on the 13.  Now today, 20th, sharp pains again on left side.  Others, nips starting to twinge, looks darker(could be hallucinating), upper stomach rock hard all the time, icky tummy in the AM, some foods I could eat before make me gag, really moody, and super tired all the time!  Took test, negative.  FYI, I have almost 7 year old twin boys!
