Symptoms come and go

We just started trying for our first this month. Two weeks ago I had tingly nipples, dizziness, fatigue with higher BBT and now a little bit of dizziness, frequent urination, and higher than average BBT.
 Since I'm just getting used to being off of my hormones and simultaniously trying for a baby I don't know if it's preganacy or just a normal cycle, but I was curious if anyone else had on and off pregnancy symptoms or if symptoms always increase instead of going away all together.
