How is this looking?

Trisha

Wondering if anyone has any input on how this is looking so far. Iv got a peak ovulation test cycle day 18 and was expecting my BBT to stay up today but it slightly went down. I take my temp every morning at 6:30 but lately iv been waking up at 5:45 because I have to pee so I take it before I get out of bed. Could this be messing with my temp or is it not that big of a difference? Any input would be great!
