Reading Clearblue Ovulation Test

[purplepoet20]

My friend is using Clearblue O Test and would like to know... with just the strips if the 2nd line is there and about halfway to full color does that mean the start of fertility???? She is also trying for a girl and doesn't want to DTD for 2 days before O because she got all 7 of her boys during that time.

yes and likely the next day will be first +opk.
(mine read this way every cycle)
Stick to one attempt dtd @ first +opk for pink.

Not necessarily. It can be normal to have tests that go a little darker and then a little lighter again.
