Whos with me cycle buddies

Hopefully we did it this month I actually started getting a flashy smiley face (high) on the 17th. I got my peak yesterday but by this morning it was low and of course my SO feels i got it enough so didn't get lucky tonight 😥😥😥. We used preseed everytime. We've done the every other day and no luck so I wanted to try everyday but ended up working out 2 days doing the BD and a day off. Hoping to convince baby #2. I know it is a 50% chance but what do ya'll think my odds are.
