I got a positive OPK yesterday morning and then I still had a positive this morning as well. Does anyone know when exactly I should be expecting ovulation? I havenโ€™t tested again to see if itโ€™s still peaking or not. I just canโ€™t figure out my window and my husband leaves for a business trip on Saturday and has been sick this week ๐Ÿ˜’๐Ÿคฆ๐Ÿผโ€โ™€๏ธ hoping for today and tomorrow but not holding my breath
