HELP, super new to this!

Mariah

So my husband and I have been married for a year now. We have decided to start trying for a baby. I got my IUD out March 1st and so far, my periods have come on the regular schedule. I have also had two now so I’m pretty confident about my cycle being regular. I ordered ovulation strips last night, and pregnancy strips. I’m gonna start tracking but have no clue where to start. When should I begin? How many days after my period? Do I have sex every day of fertilization or is it just my prime day? TIA!
