Ovulation question.

Anne
Hi Ladies,
​I've been TTC for about 10 months now but without charting anything.
​So this last week I finally began taking   my BBT
​I took antibiotics last month and my period was late so it just finished last Tuesday Nov 11. 
​Anyways, I wonder if it was possible to already be in my fertile window?
​Glow says it's not for another week but I have EWCM and for two days my BBT went up .2 and .3 degrees (C).
​Is it possible that I'm ovulating so soon after a period?
