Pregnant?

Tomorrow will be day 44 of my cycle. My cycles are anywhere from 36-40. 40 was the longest I have had since April. I have been TTC my 4th since August. I have extreme fatigue, large swollen sore breasts, and extreme hunger. I'm scared to take a test and be disappointed. Should I wait to see if Aunt Flow arrives. Is this just a late period and I'm having PMS? All my symptoms just started 2 days ago. Usually I have PMS symptoms for a week before I start.
