Expert TTC opinion. Hormonal?

T
 I had my period (as expected) on Saturday, but it was lighter than usual. Although it filled my tampax (sorry TMI) during the night i've been spotting since then. 
Because my boobs were still sore, i tested just for discart any chances, on monday and was negative. But today i've been very nauseated and my CM is crazy changing. At the same day i get watery, sticky and even kind of egg white. Also my boobs are less sore, but my skin is more oily.
I attached my BBT chart.
So you think this might be any hormonal problem (i'm TTC since 6 months now).
Sorry for my English, in advance. And thanka.
