High follicular phase BBT?

Hi, there! This is my first month charting so it's all new to me. I have higher temps in my follicular phase, around 98.0, so I don't have much higher that my body temp really rises on a potential ovulation.  I don't have a thyroid problem but I am a very restless sleeper.  It seems like my body temp doesn't go up much or fast after a potential ovulation.  Any one else?  It's making it difficult for me to track. I just hope I'm ovulating:/
