I know this is negative

I know this is a negative opk, but wondering when do you guys BD? I’m trying for my second, still breastfeeding my one year old once a day. My last cycle was 35 days long (before baby I had regular cycles). Currently on cycle day 17 and still no positive or even high opk’s.. my glow app had previously predicted tmrw as ovulation day (obviously that was wrong). Premom has been predicting CD 20. I’m also having a hard time deciphering any other ovulation signs since having a vaginal birth and breastfeeding. Cervix and CM are so different now!

We have been BD every 2 days this week as I was expecting to ovulate sooner.. not sure if I should keep it up or wait for a positive opk. It’s hard when you don’t want to make it feel like a chore but also don’t want to miss your chance. What do you guys do? Anyone else in the same boat?
