My bbt help

I've just started to record my bbt this is it to date, can someone tell me if this is normal ? Isit a good sign towards pregnacy ? My AF is due the 4 July.. But as I've said I had been experiencing some symptoms which i don't usually get before AF , also my cm im hasn't changed for a few days now still very creamy and lotion like .. Could someone give me some advise please . ?​
