Ovulation urine?

Kat

TTC #2 and I bought the Clearblue ovulation test. It says I can test with any urine, INCLUDING first morning urine. However, other things I’ve read online say NOT to use first morning urine. ????

I would prefer to do first urine since everything I’ve read says to do it the same time every day so my first urine is the best time obviously with my work schedule. That’s the only time I can assure it be done the same time everyday. 🤔 Help!
