Clear Blu negative.

So myself and the hubby have started "TTC" for about a month now... I am 5 days late for my period now and was feeling rather excited. My breasts are really sensitive and seem to be bigger than usual, which never happens on my normal cycle. I have a 32 day cycle and usually it is only a day late or early.

I had some spotting around 3 weeks ago, but at that time just thought that I had not finished fully.

This morning the hubby got me a clear blu test ,and it showed up "not Pregnant".

I didn't think I would be as sad as I am, but my body is confusing me.

Any advice?
