Anumussama

Hi... wish u all baby dust who are ttc.

I want to discuss that this month i used opk clear blue and on day 15 and 16 it shows positive but the test line was darker then the control line on day 16 of my cycle ... my cycle started 4 jan and showed positive on 18 and 19 January..

Then on 20 January which is day 17 of my cycle it was very very faint line..

Q1.....

Does it mean that i ovulated on day 16 (19 january ) ????????

Q2

I got my periods today means 2 feburary...

So article says that before 14 days of your period you ovulates so according to thT does i ovulate on 19 january means day 16??????
