HELP 💖

Hi everyone, in currently #TTC on my 3rd cycle. Do you guys think I have a chance this month?? I usually ovulate on the 14th or 15th day, only took a digital opk last night just to get it out if my thoughts; surprisingly i got a hollow circle 😖😖 what can that possibly mean? my periods are VERY regular. AF due 31st of July. Please HELP 😭😭!!!
