Ovulation assistant please!!!

Ladies,

We are trying with our 2nd and haven’t been successful so I decided to purchase Clear Blue ovulation kit (not advanced).

I’m generally 28 days so I started to test on Sunday which is day 11. Same time, used same size disposable cup, same everything. All seemed well that the blue line was getting stronger each day. Today it was much less than yesterday. According to our app, yesterday would have been my O day but the actual test didn’t say so.

How can it be getting fainter? I wish I saved everyday’s test which I will do next month.

I will try again tomorrow just to double check to see if it’s getting darker or lighter.

We haven’t even had sex yet because it’s become such a chore by the end of the fertile window, I figured don’t waste it on nothing days and when it shows the smiley face then do it 3 days in a row. Beforehand we did it everyday in the fertile window and it was too much.

The first time, we got pregnant first try without even thinking or trying ovulation kits or pressed. I think that’s why. We were planning on trying a few months later but literally last second said hey why not.

I also had my IUD removed in December but doctor said it doesn’t stop you from ovulating so I am confused and now pissed off at my myself for maybe missing my window this month.

Anyone else not receive a smiley face and it started to become fainter? Please help. My child terribly wants a sibling.
