Cycle after a iud.

Manda

So my husband and I decided on another baby, this makes number 4 for us. The youngest will be 2 in July. So my question is this is the first time trying after a iud, we removed it the 8th but now I have no clue how to track my cycle, I didn’t get my monthly during the use. We have 3 daughters and we’d really like to try for a boy using some planning but have no idea how to find my true cycle without daily ovulation tests. Help!
