JA`s Mommy👶💙

So my dr want me start tracking my ovulation days using opks. I have done this all before n there just soooo confusing!😬 I bought 7 dollar tree opks. I didnt buy the digital ones becus they r wayyy to expensive. Can someone show or explain to me a True Positive Opk?? Also is it morning or afternoon urine???

Thank u ladies💛
