I'm 6 months PP and trying to concieve baby #2

My cycle length is shorter now that I've had a baby (about 24-25 days according to period tracking app) last month I used ovulation tests, and got a positive opk on CD16. I had sex 8 days in a row since CD8 until CD16 but didn't get pregnant.

I'm currently on CD16 of this month but haven't had a positive opk yet. I've had sex every single day since CD7 and will do until my period is due and see if that works

What does everyone think my chances are if I have sex everyday???

Any suggestions or advice on concieving bub no.2 is hugely appreciated
