Cycle day 54?

So confused right now. TTC baby #2. Had mirena removed in Dec 2013. First period was in Feb 2014. Seems like my cycle is about 35 days. I'm on day 54 now and no period. I don't really feel any different- so no pregnancy symptoms. Took a test but it was null. No lines at all so I just threw it out. Sadly, I don't want to take another one because I don't want to be disappointed if it's negative and feeling a slight twinge of hope seems like a better way to go.
