Omg!!!! I had a major cystectomy back in May. My periods have been supper whack ever since! I tried to use OPKs in Oct & Nov and each time, nothing or I would start another period. Now In December, I prayed and began to use the OPKs for this month and I was getting discouraged because I had entered my “fertile week” according to the app and I hadn’t gotten one flashing face. Then one day, BAM! SOLID FACE! Sprinkle a little baby dust for me 🤞🏼has anyone else ever had that happen?
