I have been using the clear blue digital ovulation sticks and keep getting a circle rather than a smiley face.

My last period was Unusually longer and heavier than normal would this affect ovulation?

I am only 28 and my cycle can sometimes be 30, 31 or even 33 days. But last month it was only 28.

I am finding it difficult holding a wee for 4 hours and limiting fluids just to test.

I had been doing the clear blue digital in the morning for the first few tests and have since been doing them in the morning and afternoon.

Is anyone else having the same issues?
