Not sure whats occuring

Hey all,

We have been TTC for 3.5 years with zero luck. The other day I noticed more discharge than normal, my lower abdomen was bloated as if with gas, my breasts were so tender that breathing hurt, lower back was sore and I was weepy at the drop of a hat.

Three negative tests later and I'm sitting here today with no discharge, barely sore breasts...barely anything.

I'm in tears. No positive tests? No more symptoms? What happened? Is this normal, should I speak to a doctor? Maybe their tests are more sensitive?

Edit: sorry all, I'm two weeks late and typically I don't get cramps or any sort of PMS symptoms other than the day before I'm completely wiped out energy wise. None of that lately.
