Is this normal?

Bee • Expecting #1 August 2015 💕

I'm in my 2nd month of BBT charting and ive just had my dip and spike right at the end of my period? could i be ovulating already?

-My cycles are between 30-35 days long.

-I've not been sick/ poorly.

-I'm charting at the same time each day.

Is it too late to take an OPK today?

Thanks for any advice/ comments :-)
