Do we convice ourselves?

I do know exactly what you mean. The same thing happens to me and yes they do come out negative every time! : ( In fact so much that I just want to give up. I could have sworen that I was pregnant this last time because I had so many symptoms and was late 2 days on my period, well 2 days isnt really late, but either way I thought I was and comes Friday and the test is negative and then I get my period Sunday.......ugh!
